Fall 2006

Mon/Wed 12:30-2:00, 1165 Etcheverry


UPDATE: Office hours for Dec 11-Dec 15

Monday, 11-12
Tuesday, 10-11

See the computer exercises below (they are below the Homeworks). These are very important. Please do them, and answer the questions as you work through the examples.


Reading Assignments

Chapter 7, all. Should match up well with the SISO robust performance.

Chapter 8, sections 8.1-8.11. Robust stability and performance as a nonvnishing determinant condition, and then how to enforce/verify the nonvanishing det.

Homework Assignments

MIMO State Space Stabilization.

SISO Robust Performance.

Linear Algebra.

SISO, Transfer function Youla.

Limitations in feedback systems.

Fourier and Convolution.

Structured Singular Value. Do problems 2, 3, 8, 9, 10, 14 and 15. Reread problem 1 before doing problem 14.

Lyapunov/Riccati. Do problems 1, 2, 3, 4, 6, 9, 10.

Hinf Inequality Analysis. Do problem 3.


Computer Exercises

Introduction to structured singular value.

Introduction to robustness analysis.

Introduction to HinfSyn. You will need the m-file script himatModel.m. It has the aircraft model and weighting functions for the example.

example0.m, elementary McFarlane/Glover Loopshaping example.

example1.m, SISO McFarlane/Glover Loopshaping example for 2-mass resonant system; supporting functions, pistage.m, lagstage.m.

illconditionedplant.m, DK iteration for 2-by-2 ill-conditioned plant.
