Course Description
Linear control system representation in time and frequency domains, feedback control system characteristics, performance analysis and stability, and design of control.
Learning Outcomes
By the end of this course, the student will be able to:
- Model – via differential equations or transfer functions – electrical, mechanical and electromechanical dynamical systems
- Linearize a set of nonlinear dynamical equations
- Create a second-order model from a system's step response
- Construct all-integrator block diagrams from a transfer function, a set of differential equations, or a state-space representation and vice versa
- Compute a state transition matrix from a system matrix
- Describe -- in terms of percent overshoot -- settling time, steady-state error, rise-time or peak-time how the poles of a second-order continuous-time system influence the transient response
- Translate design specifications into allowable dominant pole locations in the s-plane
- Calculate a system's steady-state error and how the steady-state error can be influenced via system parameter changes
- Construct and interpret the Routh array.
- Determine the stability of a closed-loop system
- Calculate a system's sensitivity with respect to different parameters
- Sketch the root locus associated with a transfer function
- Design analog controllers using root locus techniques
- Design an analog PID controller to meet design specifications
- Calculate the phase margin and gain margin of a system from its frequency response (Bode plots)
- Design analog controllers using Bode plot techniques
- Design full-state feedback gains to achieve acceptable closed-loop behavior
