Specific Goals Define the control system design problem and develop a preliminary appreciation of the tradeoffs involved and requirements for robust stability and performance. Develop concepts and tools for ultimate state error analysis. Develop the relationship between time domain and frequency domain performance specifications, e.g, rise time, overshoot, settling time, sensitivity function and bandwidth. Develop frequency domain design methods, including: the root locus method, Nyquist & Bode methods, and stability margins. Provide an introduction to state space design: controllability and observability, pole placement, design via the separation principle (time permitting).
