摘要： In-forward-rotation command information is obtained by sampling command signals during one or more rotations of a rotary shaft in a constant speed region while a motor is driven in a forward drive pattern including the constant speed region where the rotary shaft rotates in a forward direction at a constant speed. In-reverse-rotation command information is obtained by sampling the command signals during one or more rotations of the rotary shaft in a constant speed region while the motor is driven in a return drive pattern including the constant speed region where the rotary shaft rotates in a reverse direction at the constant speed. Correction data is generated using the in-forward-rotation command information and the in-reverse-rotation command information.

摘要： A method for determining the rotating position of the drive shaft of a commutated direct current motor by evaluation the current ripple contained in the armature current signal, wherein the metered result of the detected current ripple is corrected when erroneous ripples or double ripples are present. According to the information, determination occurs after detection of a current ripple at a point in time kt t0 at a subsequent point in time or at several subsequent points in time t1...n, the time interval between each subsequent point in time t1...n and the point in time t0 of the previous detection of the current ripple being smaller than the period of the current ripple, whereby the angle of rotation which is set back from the moment t0 of detection of the current ripple is calculated on the basis of actual motor current data and motor characteristic data and, from there, the expected moment in time of the next current ripple detection is calculated. The metered current ripple result is corrected if the expected moment in time resulting from the calculation and the moment of real current ripple detection do not coincide with each other.

摘要： A method for correcting the determination of the rotational position of a commutated d.c. motor drive shaft, by evaluating the current ripple contained in the armature current signal when double or missing ripples occur. The method is characterized by a first step wherein a spectral analysis of the armature current signal concerning the frequency components thereof is carried out. The actual frequency of the of the current ripple contained in the armature current signal, which occurs during operation of the d.c. motor and which has been obtained from the spectral analysis, is monitored to detect sudden changes in said frequency; and, if a sudden change in the actual current ripple frequency is detected, a correction of the current ripple meter reading is carried out.

摘要： An actuator position control system for brush-type DC motors. The system includes a sensing inductor, amplifier, central control unit (microprocessor), and motor driver. The system utilizes the differential signal di/dt to indicate the falling edges of commutation spikes in the motor current profile. An inductor is selected as the signal sensor, because voltage drops across the inductor are directly proportional to di/dt. The voltage drop, L(di/dt), across the inductive sensor is input to the amplifier, amplified, and then sent to the microprocessor. The microprocessor reads the output pulses from the amplifier and compares the pulse count to an input command signal. The microprocessor then sends shaft position control information to the motor driver.

摘要： The invention relates to a method for determining the position of an element driven by the drive shaft of a direct current motor within a predetermined displacement trajectory between two block positions, by evaluating the current fluctuations contained in the armature current signal. According to said method, when the driven element is displaced into a block position, a normalization in relation to said block position is carried out. The method is characterised in that the direct current motor is triggered to manoeuvre the driven element into the block position when a signal for manoeuvring the driven element out of its block position is present and that the system carries out a normalization in relation to the current block position, when the driven element lies in the block position that has been determined, before the direct current motor is triggered to manoeuvre the displaceable element out of its block position, in accordance with the signal that is present.
