A hybrid track seeking fuzzy controller for an optical compact disc player is proposed. It is shown that the proposed hybrid fuzzy controller smoothes the applied voltage to the sled motor and improves the track seeking efficiency. The proposed hybrid fuzzy controller consists of three subsystems including parking time controller, driving force controller and parameter tuner. All three of subsystems are designed based on fuzzy inference. The hybrid fuzzy controller will on one hand drive the pickup head as fast as possible to the neighborhood of target track, it will on the other hand smoothly park the pickup head so that the fine seek controller can take over the control of pickup head
