碩士 === 國立成功大學 === 機械工程研究所 === 82 === For the controller design, the sliding mode control is a simple method , because it needs only to define a suitable equation of the sliding hyperplane according to the required performance. herefore , it isn't so necessary to find a mathematical model of the system. Usually, only a sliding hyperplane is required to design the sliding mode controller. The higher uncertainty the system has, the chattering happens easily it will. In this paper, we utilize the region of the two sliding hyperplanes as the required range of the sliding mode for the control system, and through the fuzzy control theory to decide the control signal. Through the position and tracking control of a ball screw driven by a pneumatic servomotor , in the paper, one knows that the regional sliding mode fuzzy controller is a new successful controller , which combined both the properties of sliding mode and fuzzy control.
