ABSTRACT:
An apparatus for controlling a dynamic system, for example, a continuously variable transmission for an automotive vehicle which adjusts a gear ratio by bringing a pulley position of a primary pulley into agreement with a target one through a hydraulic system under the feedforward and sliding mode control is provided. The apparatus calculates a feedforward-controlled variable in addition to a feedback-controlled variable and adjusts the pulley position of the primary pulley to a target one using the hydraulic pressure provided based on the sum of the feedforward-controlled variable and the feedback-controlled variable, thereby enhancing the robustness of the sliding mode control without causing the hunting.
