Abstract:
1. A sliding mode control apparatus, wherein, when displacing a controlled object to which an urging force is applied by an elastic member from one displacement end to an other displacement end, the control apparatus sets a switching hyperplane and controls the controlled object by using a sliding mode control in such a manner that a state quantity of the controlled object is converged on the switching hyperplane, wherein, in the sliding mode control, the control apparatus switches an operation mode for controlling the controlled object when the controlled object passes an operation switching point provided in a displacement region of the controlled object, the control apparatus comprising: a disturbance detecting section that detects disturbance in the sliding mode control; and a changing section that changes the operation switching point in accordance with the disturbance detected by the disturbance detecting section.
