摘要： 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.
摘要翻译：一种用于控制动态系统的装置，例如用于机动车辆的无级变速器，其通过在前馈和滑动模式控制下通过液压系统使主滑轮的滑轮位置与目标滑轮位置一致来调整齿轮比被提供。该装置除了反馈控制的变量之外还计算前馈控制变量，并且使用基于前馈控制变量和反馈控制变量之和的提供的液压压力来将主滑轮的滑轮位置调整到目标控制变量从而提高滑动模式控制的鲁棒性，而不会引起振动。

摘要： A slip control apparatus provides a smooth response of actual slippage amount during a transitional period when a lock-up clutch is shifting from a disengaged state to a slipping state, and quickly determines a response to external disturbances when the slipping of the clutch is in a steady state. The apparatus has a first control unit for outputting a first control value based on the difference between target slippage amount and actual slippage amount, a second control unit for outputting a second control value based on the actual slippage amount, and a clutch pressure regulating unit for controlling an electromagnetic valve to control a lockup system on the basis of the sum of the first and second control values. The first control unit performs control for the transitional state of the lock-up clutch between the disengaged state and the slipping state. The second control unit performs control in response to external disturbances when the slipping of the clutch has reached the steady state via the transitional state.
摘要翻译：滑动控制装置在锁定离合器从分离状态转移到滑动状态的过渡期间提供实际滑动量的平滑响应，并且当离合器的滑动处于一个状态时，快速地确定对外部干扰的响应稳定状态。该装置具有第一控制单元，用于基于目标打滑量和实际滑移量之差输出第一控制值，基于实际滑差量输出第二控制值的第二控制单元和用于输出第二控制值的离合器压力调节单元，根据第一和第二控制值之和来控制电磁阀来控制锁定系统。第一控制单元对脱离状态和滑动状态之间的锁止离合器的过渡状态进行控制。当离合器的滑动经由过渡状态达到稳定状态时，第二控制单元响应于外部干扰进行控制。
