Analysis of Methodology and Solution Strategies in Digital Control System Analysis and Design (3rd Ed.)

Subject: Digital Control Systems Authors: Charles L. Phillips & H. Troy Nagle Edition: 3rd Edition Objective: To deconstruct the problem-solving methodology required for mastering the text.

Use the Bilinear Transform: $z = \fracw+1w-1$ to map the $z$-plane to the $w$-plane.
Apply standard Bode plot techniques (gain crossover, phase margin) on the $w$-plane.
Design a filter $D(w)$.
Transform back to $z$: $D(z) = D(w)|_w=\fracz-1z+1$.

4. Stability in Discrete Time

Bounded-Input, Bounded-Output (BIBO) stability: all poles of G(z) strictly inside the unit circle.
Jury stability test: algebraic test for polynomial roots inside unit circle—useful for hand analysis.
Lyapunov stability (state-space): existence of P > 0 satisfying Φ^T P Φ - P = -Q for Q > 0.

10. Practical Considerations and Pitfalls

Choosing sampling rate: too slow → aliasing, poor performance; too fast → excessive computation, quantization problems.
Model mismatch: discretization and plant uncertainty necessitate robustness checks.
Quantization: both sensor resolution and coefficient quantization can destabilize fragile designs; prefer pole locations away from unit circle and scale gains conservatively.
Implementation delay: computation delays effectively increase sampling period—include in design as multiplicative z^-d factor.
Anti-windup for digital integrators to handle actuator saturation.
