Electric power steering control device |
摘要 |
Provided is a control device for an electric power steering device, the control device configured to control an output torque of a motor that provides an assist torque to a steering torque, the output being controlled based on a steering-torque signal from a torque sensor that detects a steering torque, the control device controls the output torque using a correction signal to damp a vibration at a natural frequency determined in accordance with a transfer characteristic from the steering-torque signal to the output torque. |

1. A control device for an electric power steering device, the control device configured to control an output torque of a motor that provides an assist torque to a steering torque, the output torque being controlled based on a steering-torque signal from a torque sensor that detects the steering torque,
wherein the control device controls the output torque using a correction signal to damp a vibration at a natural frequency determined in accordance with a transfer characteristic from the steering-torque signal to the output torque, wherein the output torque is controlled by using an assist-torque signal proportional to a signal obtained by negatively feeding back the correction signal to the steering-torque signal as a current command corresponding to a command value of the output torque, wherein the correction signal includes a value obtained by multiplying a motor-speed signal from a motor-speed detector that determines a rotational speed of a rotary shaft of the motor by a gain. |
