Closed-loop system with output feedback controller Consider the closed loop system u Plant y K ̂x Observer Output feedback controller where Plant: σx = Ax + Bu, y = Cx + Du Observer: State feedback controller: σ̂x = Âx + Bu − L(y − Ĉx − Du) u = K̂x ELEC 3035 (Part I, Lecture 7) Observer design 10 / 12
Feedback controller: σ̂x = (A+LC)̂x +(B + LD)u − Ly, = (A+LC + BK + LDK)̂x − Ly u = K̂x Note: the feedback controller is a dynamical system Closed-loop system: [ [ ] x̂x] A BK σ = −LC A+LC + BK][ x̂x Note: closed-loop system order = plant order + controller order Error equation: [ [ ] x A+BK −BK x σ = e] 0 A+LC][ e ELEC 3035 (Part I, Lecture 7) Observer design 11 / 12
