Abstract
A motor control device for controlling drive of an electric motor that controls a steering angle of a steering device, the motor device includes: a torque sensor and an electronic control unit. The torque sensor is configured to detect steering torque acting on a steering member. The electronic control unit is configured to: generate a steering angle command value based on the steering torque by using an equation of motion that is a reference model of the steering device; control driving of the electric motor so that an actual steering angle follows the steering angle command value; and limit a virtual reaction force that is a reaction force component of the equation of motion.
