Abstract :
The optimal projection approach to fixed-order dynamic compensation is merged with the guaranteed cost approach to robust stability and performance to obtain a theory of reduced-order, robust control design. The principal result is a system of modified Riccati and Lyapunov equations which explicitly characterize robust dynamic controllers of fixed dimension.
