本校提出模糊解耦合控制運算法則。爲達到解耦合之目的,本方法採用二階層控制方式。在第一階段中,首先藉由建立在古典的線性系統理論上之模糊控制器將一個耦合之系統分解爲互相獨立之兩個次系統。在第二階段中,再使用傳統的糢糊控制器個別的控制兩個次系統;此模糊控制器被應用在光碟機複合式讀寫頭的控制模擬。複合式讀寫頭是由驅動器所組成,解耦合控制器將系統分解粗調與微調兩個次系統。結果顯示模糊解耦合控制器相當適合光碟機複合式讀寫頭的控制。
This paper presents a fuzzy decoupling control algorithm. In order to achieve both decoupling and regulation. A two stage control scheme is adopted. In the first stage the system is decomposed into uncoupled subsystems by using a controller based on fuzzy logic. The decoupling fuzzy logic is derived based upon the classical linear system theory. In the second stage, conventional fuzzy controllers are designed to manimuplate the performance of the individual subsystems. The fuzzy controller is applied to the control of a optical disk drive compound actuator, Simulation results show that the fuzzy decoupling controller is especially suitable for compound actuator control implementation. The decoupling controller decomposes the system into the coarse actuator input and the relative displacement between the two actuators. Specifications for the control of the compound actuators are derived, and their effects are demonstrated.
