摘要： A position controller for controlling an electric motor comprises first position control circuit which provides first speed signal, second position control circuit which controls a mechanical system simulating circuit and provides second speed signal, an adder which adds the first and second speed signals to provide third speed control signal, first speed control circuit which receives the third speed signal and provides first torque signal, second speed control circuit which provides second torque signal, third speed control circuit which provides third torque signal, and an adder which adds the first, second and third torque signals to provide final torque signal. The output torque of the electric motor is controlled so that the output torque coincides with a torque represented by the final torque signal. The position controller has high-speed response characteristics, is capable of suppressing mechanical vibrations and maintains a constant response frequency even if the moment of inertia of a load machine driven by the electric motor varies.
