Servo steering control system with steering torque sensor and servo motor of motor control circuit also microcomputer which is connected with steering torque sensor and microcomputer has phase compensation section

摘要

The servo steering control system is provided with a microcomputer (10) which has a phase compensation section (2). This section provides a control signal by a further conducting or further processing of the steering torque signal, if a steering is operated with a higher speed than a specified value. The microcomputer also has an amplification control section (3), which provides a noise suppression signal by a suppression of high frequency components of the control signal, which are higher than a specified frequency and a control amount computing section (4), which provides a control amount signal based on the noise suppression signal.
