1. Introduction to Exponential Functions
2. Step Response For First Order System H(s) = a / (s+a) (a > 0) For Different Values of Parameter a, Speed of Response Decreases With Increasing a
3. Frequency Response For First Order System H(s) = a / (s+a) (a > 0) For Different Values of Parameter a, System Bandwidth Increases With Increasing a
4. Pole Dependence on Damping Factor for Standard Second Order Systems
5. Step Response Dependence on Damping Factor for Standard Second Order Systems, Dependence of Overshoot on Damping Factor (Undamped/Underdamped Case)
6. Step Response of a Second Order Underdamped System With Zero In Numerator, Effect of Zero On Step Response, As zero moves further into left half plane its derivative action becomes less pronounced, As zero moves closer to origin its derivative action becomes more pronounced.
7. Root Locus For Nominal Second Order System - Nominal CLS Stable for all Non-negative k, Effect of A Third Pole - CLS Goes Unstable For Large k, Effect of Varying Third Pole With Gain k Fixed
8. Feedforward Compensation Can Reduce Overshoot Caused By Zero (Derivative Action) In Series PI Compensator, Closed loop response to step reference command: (i) with series and no feedforward compensation, (ii) with series and feedforward compensation
9. Introduction to Routh Table: Some Examples
10. Introduction to Frequency Responses: Some Simple SISO Systems
11. Reading Off Stability Margins from A Frequency Response: Unstable Second Order Nonminimum Phase System, Relating Bode and Root Locus Ideas
