摘要： A position shift control apparatus is provided which includes an electrical motor joined to an object through an output shaft and a torque transmission mechanism, a detent mechanism producing elastic pressure to hold the object at a target position, and a motor controller. When torque, which is created by the elastic pressure produced by the detent mechanism and acts on the output shaft during rotation of the motor, is opposite in orientation to that outputted by the motor, the motor controller determines the angular position of the motor, as sampled upon a change in an output from an output shaft position sensor, as a reference angular position of the motor for use in controlling the position of the motor, thereby resulting in a decrease in mechanical load on the detent mechanism and the torque transmission mechanism to ensure the durability and operation accuracy of the apparatus.

摘要： A synchronous motor controller is provided which is designed to diagnose whether a failure is occurring or not in energizing one of phase windings of a synchronous motor which is required to be energized first to start the synchronous motor. When such a failure is found, the controller reverses the synchronous motor slightly to bring one of the phase windings which is possible to energize properly to a starting position where the energization of the phase windings is to be initiated to start the synchronous motor in a required direction, thereby ensuring the stability in starting the synchronous motor even if any of the phase windings is failing to be energized.

摘要： The rotational phase difference between an engine crankshaft and an engine cam shaft, and a mechanism which controls the difference between the two is controlled using closed-loop feedback. The close-loop feedback has a learning function so that the rotational phase difference between the crankshaft and the cam shaft converges on a target value. The learning process uses retaining outputs based on the engine operational state to compensate the degree of actuation of the rotational phase adjusting mechanism with the value thus learned. The deviation relative to the retaining output from a map based on a variation speed at each rotational phase difference, and this deviation is added to a delay output of the feedback loop at each iteration.

摘要： To realize a highly reliable feedback control of the valve timing, i.e., angular rotational relation between a crankshaft and a camshaft, three reference signals are generated from the crankshaft side, and three cam signals corresponding to three pulse inductors arranged at even angles to the camshaft or arbitrary angle intervals to the camshaft are generated from the camshaft side. The variation in the phase difference of each cam signal to each reference angle signal caused by the installation position of the corresponding pulse inductors is stored in a memory as compensation values indicating differences from the phase difference used as a reference. When the signals are detected, the corresponding compensation value for the phase differences other than those used as reference is read out, added and compensated. Based on the relation of the compensated phase difference and a target value of the valve timing, the rotational phase of the crankshaft and the camshaft is controlled.
