This document provides an introduction to system dynamics and mathematical modeling of dynamic systems. It defines key concepts such as:
- A system is made up of interacting components that work together to achieve an objective. It has inputs from the environment and outputs responses to those inputs.
- Dynamic systems have outputs that vary over time even if inputs are held constant, due to internal feedback loops within the system.
- Mathematical models of dynamic systems use equations, often differential equations, to describe the system's behavior based on physical laws. The accuracy of a model's predictions depends on how well it approximates the real system.
- Engineering systems like mechanical, electrical, thermal and fluid systems can all be modeled as dynamic systems using appropriate equations

Model-based Investigation of the Effect of Tuning Parameters on a
Servo-Motor Response and Mode Transition
1.0 Project Objective:
The objective of this project is to familiarize the students with the use and limitations of
models in understanding the response of a practical servo-system and evaluating its
usefulness. It introduces system modes as a tool of evaluating the quality of a system’s
output. It also explores the ability of a controller’s tuning parameters to affect the
system’s behavior and cause it to shift from one mode to another.
2.0 Equipment: Matlab, Simulink and the EE380 textbook.
3.0 Background:
This section provides a brief background about the tools and concepts needed to
understand the role of mathematical constructs in modeling, predicting and tuning the
behavior of a system.
3.1: System Modes and the Quality of its Response
Control systems are enablers whose objective is to make a servo-process (SP) yield to
the commands of an operator and provide him with useful work. When the operator
issues a command, the SP can only respond by being in one of the following modes:
o If the SP complies with the command of the operator it is in a stable mode
o If it does not comply with the command, the mode is called unstable
Figure-1: Stability does not imply useful outcome from the servo-process
Obviously, the minimum expectation of the operator from the servo-process is to be in a
stable mode. However, the system being in a stable mode need not necessarily mean
that it is providing the operator with useful work. The quality of the system response could
be too poor and practically useless. Take for example a car as a servo-process (figure-1).
If the car fails to reach the destination, one may call the process unstable. However, if the
process is stable and the car is able to reach the destination but the path it took is too
long, rough, consumes too much fuel and contains many detours, the effort derived from
the car cannot be called useful.
Measuring the usefulness of the outcome from a servo-process is important since a
response that is not useful defeats the purpose of control. One way to assess the quality
of a system’s response is though the use of performance measures such as overshoot,
settling time, rise time and steady state error. A more general way of describing the
quality of system behavior is through using system modes. System modes may be used
to qualitatively describe the whole state of the response not particular aspects of it, as in
performance measures. In industrial applications, six system modes are used to
describe the response of a practical servo-process. They are unstable, over-damped,
critically-damped, under-damped, oscillatory and chattering. Their description and profile
are shown in table-1.

Control system basics, block diagram and signal flow graphSHARMA NAVEEN
This document discusses control systems and provides definitions and classifications of control systems. It defines a control system as an arrangement of physical elements connected to regulate, direct or command itself. Control systems are classified as natural or man-made, manual or automatic, open-loop or closed-loop, linear or non-linear. The key difference between open-loop and closed-loop systems is that closed-loop systems have feedback which makes them more accurate, reliable and less sensitive to parameter changes compared to open-loop systems. Examples of both open-loop and closed-loop systems are provided. The document also discusses transfer functions, Laplace transforms, block diagram reduction rules, and signal flow graphs.
This document provides an overview of control systems, including:
- Defining the basic components and configurations of control systems
- Describing open-loop and closed-loop systems, their advantages and disadvantages
- Classifying control systems as single-input single-output, multiple-input multiple-output, linear, non-linear, time-variant, or time-invariant
- Outlining a 6-step general process for designing a control system
- Assigning an activity for students to describe the operation of a control system from a selected sector by reverse engineering it according to the design steps

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

# Scenario Covered:
- Basics of IAM in AWS
- Implementing IAM Policies with Least Privilege to Manage S3 Bucket
- Objective: Create an S3 bucket with least privilege IAM policy and validate access.
- Steps:
- Create S3 bucket.
- Attach least privilege policy to IAM user.
- Validate access.
- Exploiting IAM PassRole Misconfiguration
-Allows a user to pass a specific IAM role to an AWS service (ec2), typically used for service access delegation. Then exploit PassRole Misconfiguration granting unauthorized access to sensitive resources.
- Objective: Demonstrate how a PassRole misconfiguration can grant unauthorized access.
- Steps:
- Allow user to pass IAM role to EC2.
- Exploit misconfiguration for unauthorized access.
- Access sensitive resources.
- Exploiting IAM AssumeRole Misconfiguration with Overly Permissive Role
- An overly permissive IAM role configuration can lead to privilege escalation by creating a role with administrative privileges and allow a user to assume this role.
- Objective: Show how overly permissive IAM roles can lead to privilege escalation.
- Steps:
- Create role with administrative privileges.
- Allow user to assume the role.
- Perform administrative actions.
- Differentiation between PassRole vs AssumeRole

15. Definitions
System: A combination of components acting together to perform a
specified objective. The components or interacting elements have
cause-and-effect (or input/output) relationships. We will
investigate mechanical, electrical, fluid, and mixed systems.
Dynamic system: The current output variables of a system depend
on the initial conditions (or stored energy) of the system and/or the
previous input variables. The dynamic variables of the system (e.g.,
displacement, velocity, voltage, pressure, etc.) vary with time.
Modeling: The process of applying the appropriate fundamental
physical laws in order to derive mathematical equations that
adequately describe the physics of the engineering system.
16. Definitions
Mathematical models: A mathematical description of a
system’s behavior, usually a set of differential equations for
a dynamic system
Simulation: The process of obtaining the system’s
dynamic response by numerically solving the governing
modeling equations. Simulation involves numerical
integration of the model’s differential equations and is
performed by digital computers and simulation software.
System analysis: The use of analytical calculations or
numerical simulation tools to determine the system
response in order to assess its performance.
