摘要：

The design of a proximate time-optimal set-point servo (PTOS) controller is presented for typical double-integrator servo systems with disturbances. The controller exercises the maximum control authority for fast targeting whenever possible and then switches into linear control for smooth settling. An integration action is introduced within the linear working region so as to remove the steady-state error caused by unknown distur- bances. A state observer is adopted to estimate the un-measured speed signal for feedback control. In the presence of speed constraint, a speed regulation stage is incorporated be- tween the PTOS acceleration and deceleration stages. The control scheme is then applied to the position regulation in a permanent magnet synchronous motor servo system. Ex- perimental verification has been conducted, based on the TMS320F28335 digital signal controller board. The results confirm that the servo controller can track a wide range of set-point targets fast and accurately, and has some robustness against parameter varia- tions. © 2015 ICIC International.
