A PI/PID controller that generates a torque compensation value KPID through PI control or PID control, from a deviation between an allowable rotation speed and a rotation speed of a wheel; an adder that adds the torque compensation value to a torque command input value received from a higher-order controller, thereby obtaining a torque command output value; and a dead time compensator that has a control target model including a dead time and that applies a dead time compensation in generation of the torque compensation value by the Smith method. An input to the dead time compensator is an output of a P compensation or a PD compensation excluding an I compensation from a PI compensation or a PID compensation.
