Control Relevant Identi cation and Servo Design for a Compact Disc Player
نویسندگان
چکیده
The application of control relevant modeling of a radial servo loop in a CD (Compact Disc) player is presented in this chapter. The modeling is based on an identi cation algorithm that uses experimental data obtained from closedloop experiments to nd a low-order feedback relevant linear discrete time model for model-based servo control design. In this procedure a plant model is identi ed in terms of a normalized coprime factorization. Enhanced performance controllers are designed and implemented, and it is shown how estimated model uncertainty bounds can be used to verify robust stability of the designed controller prior to implementation.
