An improved PI controller adopting on-line self-adjustment technique of proportional control and recursive integral control is proposed to regulate the active part absorbing or releasing active power.

This paper aims at the computer process control system , introducing on-line self-adjustment paramenter fuzzy controller and applying to control the liquid-position,temperature.

The selfadaptive fuzzy-PID composite control is implemented via the fuzzy switching arithmetic based on trapezoidal membership function and the online self-tuning arithmetic with quantized and proportional factors based on variable universe and human simulating intelligence.

This paper puts forward a new-style fuzzy control way by uniting fuzzy control of online adjusting parameter and intelligent control.

This paper introduces the on-line adjustment principle and the process of safety valve adjustment,application of on-line adjustment device in safety valve adjustment of boiler in power station.

In order to overcome the drawback of the generalized predictive control(GPC) in the parameters tuning,a new GPC based on the design of double softness parameters is presented by using BP neural networks,in which the on-line tuning of the input softness parameter and the output one is achieved.
