Abstract
A motor control device main unit includes a pressure command signal generation module, a simulated pressure control module, a simulated position calculation module, a simulated pressure signal generation module, a pressure control module, a speed control module, and a current control module. The speed control module receives a motor speed command signal, which is a signal of a sum of an actual motor speed command value of an actual motor speed command signal from the pressure control module and a simulated speed calculated value of a simulated motor speed signal. The speed control module carries out speed control calculation based on a motor speed command value of the motor speed command signal and an actual motor speed of an actual motor speed signal.
