Course 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.
