Abstract
A speed controller includes a speed integration compensation low-pass filter, an integral control system, a proportional control system, and a multiplication device means. The speed integration compensation low-pass filter has a transfer function corresponding to a delay of a speed control system. The integral control system 136 is multiplied by an integral gain by a multiplier and integrated by a speed integrator before being supplied to an adder. The adder adds an output of the proportional control system and an output of the integral control system and outputs the result to the multiplier, which in turn multiplies the output of the adder by a proportional gain and outputs the result as a torque command. The multiplication means multiplies the output of the integral control system and the output of the proportion control system by a speed proportional gain and outputting the value of the torque command.
