μ‐synthesis for a compact disc player

SUMMARY This paper considers the design and implementation of robust multivariable controllers for a compact disc mechanism.The design objective is to achieve good track-following and focusing performance in the presence of track disturbances, external mechanical shocks and structured norm-bounded plant uncertainty. This robust performance problem has been solved in the k-framework using the DK-iteration scheme. Limits of implementation necessitate the use of sophisticated model reduction techniques and the use of two parallel digital signal processors. ( 1998 John Wiley & Sons, Ltd.
