Paper Abstract

A high-precision energized power supply was designed and developed based on the thought of expert self-tuning control, which was a combination of expert system and conventional PID (Proportional-Integral-Derivative) control. During the control process, the algorithms of increment PID and hierarchical integral were adopted to eliminate the phenomenon of integral saturation; and expert tuning rules were used to implement parameters trimming for the higher precision of the system. The advantages of the expert system and the conventional PID control were incorporated in the expert PID control system, namely the expert experience and the adaptive characteristics were sufficiently applied for the control performance of human-like empirical techniques. Therefore, higher steady-state precision and better dynamic response performance could be obtained. Experimental results show that the output voltage precision of the power supply is ±0.05%, much higher than the ones based on conventional PID control.
