## Study Notes

### Control Systems

• Poles and zeros characterize the frequency response and stability of a control system in a transfer function.
• In power systems, the primary purpose of voltage control is to maintain a stable and optimal voltage level.

### Optimal Control Theory

• The main focus of optimal control theory is to find the best control signal that minimizes or maximizes a performance criterion.

### Controllability and Observability

• Controllability refers to the ability to drive a system from an initial state to a desired final state in a finite time using an appropriate control input.
• Observability refers to the ability to determine the current state of a system from its output measurements.

### Root Locus Method

• The root locus method primarily focuses on the movement of poles of the transfer function as a parameter varies.

### Frequency Control and Stability Analysis

• The primary purpose of frequency control in electric power systems is to maintain a stable and optimal frequency level.
• The Routh-Hurwitz theorem provides a method for determining the stability of equilibrium points in non-linear control systems.

### Transfer Functions

• Poles and zeros of a transfer function characterize the frequency response and stability of a control system.
