Relationship to Student Outcomes
No student outcomes specified.
Course Learning Outcomes. Students will:

1. Represent systems using Laplace Transforms and block diagrams.

2. Compute transient response and calculate unit step response characteristics

3. Understand feedback characteristics and steady-state error

4. Understand stability and the Root Locus method

5. Understand frequency response and Bode plots

6. Analyze stability in the frequency domain and by using the Nyquist stability criterion

7. Specify closed-loop pole locations and frequency response characteristics (Phase Margin, crossover frequency, error constants) for achieving transient and steady-state response specifications

8. Design PID and lead/lag controllers to achieve transient and steady-state response specifications via root locus and frequency response methods

9. Use MATLAB to plot system response, draw root locus and select gain to place closed-loop poles, draw Bode/Nyquist plots and identify PM, GM, crossover and bandwidth frequencies

Professional Component

Contributes toward the Engineering Topics and/or Design experience for both Mechanical and Aerospace Engineering majors.

Design Content Description

The students learn basic control design techniques. Using Matlab, they use iteration, simulation and trial and error techniques to design controllers to meet performance specifications. Many of these problems are open-ended since there are many possible control designs that meet the performance criteria. Design problems are a major component of each portion of the elements of the grade.
