摘要： A control system and method for controlling position of a device by replacing the combination of a feedforward term, a calibrated step, and an integration term in a control scheme with an adaptive feedforward term. An embodiment is provided including a flow control valve on an internal combustion engine. The invention includes characterizing the flow control valve, and determining an error term, based upon monitored position and commanded input to the flow control valve. The adaptive feedforward term is determined based upon the monitored position, the characterization of the flow control valve, and the error term. The flow control valve is controlled to a position, based upon the adaptive feedforward term and the error term. When an absolute value of a derivative term, i.e. a time-rate change of the monitored position, is less than a preset value, the control system updates the characterization of the flow control valve.

摘要： An improved cruise control which produces a desired throttle position that is based in part on a selectively updated integral term. The integral term is only updated when the magnitude of the speed error exceeds a predefined value, thereby eliminating changes in the integral term when the speed error is smaller than the predefined threshold. In other words, the integral term is dynamic and responsive to a current error condition when the speed error magnitude exceeds the threshold, and static when the speed error is within the threshold. In this way, the operational advantages of the integral term are retained while avoiding its disadvantages, and the transition between the static and dynamic states of the integral term are smooth and seamless.

摘要翻译： 改进的巡航控制，其产生部分地基于选择性地更新的积分项的期望的节气门位置。 积分项仅在速度误差的大小超过预定值时更新，从而当速度误差小于预定阈值时消除积分项的变化。 换句话说，当速度误差幅度超过阈值时，积分项是动态的并且响应当前的误差状态，当速度误差在阈值内时，该积分项是静态的。 以这种方式，整体术语的操作优势得以保留，同时避免其缺点，并且积分项的静态和动态之间的过渡是平滑无缝的。
