    摘要: A control system for an engine throttle valve actuator uses an actuator position feedback loop with a compensation factor which applies a reverse voltage having an amplitude based on actuator momentum to a DC motor to effectuate an electrical braking action to achieve high speed response with positional accuracy. A separate position limiting feedback loop is used to prevent excessive actuator excursions. The engine throttle valve is controlled to a selected position by using a throttle valve position feedback loop and a compensation factor to provide a feedback signal to a summing junction.

    摘要: An adaptive control system and method for a vehicle window. The system and method include sensors for determining a motor current corresponding to a window position and for detecting a motor stall, and an electronic control module (ECM) for providing a position counter having a count representing the window position. The ECM is also provided for setting, independent of a dedicated motor actuation input signal, a second historical limit equal to the count when the window is driven by the motor toward the closed position and a motor stall is detected, as well as setting, independent of a motor actuation input signal, the second historical limit equal to the difference between the second historical limit and the count, and the count equal to a first historical limit, respectively, when the window is driven by the motor toward an open position and a motor stall is detected. The ECM is further provided for generating a first control signal operative to halt operation of the motor when the count equals the first historical limit, and generating a second control signal operative to halt operation of the motor when the count equals the second historical limit.
