Four wheel steering system with closed-loop feedback and open-loop feedforward |
摘要 |
An improved rear steering control system employing separate closed-loop feedback controller and open-loop feedforward control paths. The response characteristics of the open-loop and closed-loop control paths are separately scheduled to optimize the overall system performance. In particular, the authority and delay properties of the two paths are independently varied to achieve desired control objectives. As a result, the advantages of both open-loop and closed-loop control are achieved with a single control system.
