“…As can be seen from this figure, Fuzzy-PID controller performs better than other hybrid controllers in terms of settling time, POS and steadystate error. As previously reported [16], the error of the fuzzy-based PID controller is equal to zero in the steady-state. For this reason, Fuzzy-PID was selected for this application.…”

Conventional proportional integral derivative (PID) controller is widely used in many industrial applications due to its simplicity in StmctllIe and ease of design. However, it is difficult to achieve .the desired control performance in the presence of unknown nonlinearities, time delays, disturbances as well as changes in system parameters. Consequently several PID models have been suggested so at to alleviate these effects on the performance of the PID controllers. One such method is based on fuzzy logic technique which is considered much more appropri.ate when precise mathematical formulation is infeasible or difficult to achieve. Furthermore, some applications such as semiconductor packaging, computer disk drives, and ultra-precision machining require a fast and high precision processing. Consequently, there is the need to consider digital signal processor (DSI?)-based fuzzy PID for use in such applications. Design and implementation of such technique is proposed in this paper. Results of simulation studies haw demonstrated the feasibility of this controller since: it produces fast response with smooth motion control.

As the High frequency link (HFL) SPWM inverter possesses highly nonlinear property and variable parameters due to its special structure, the perfect control can not be obtained with conventional control methods especially under nonlinear load. A Self-adaptive Fuzzy Control scheme in this paper is proposed for a single-phase high frequency isolated DC\AC\AC inverter, in which a novel assistant Fuzzy Controller is designed to improve the self-adaptive and robust property by adjusting the scaling factor on-line. It takes a role to provide stronger control action for a large voltage error and a smoother control action for a small voltage error considering synchronously the error change. This in turn ensures that high quality output voltage is always maintained on HFL while the transient response improved regardless of the loading property. Simulation and experiment results of 1.5kW prototype are shown in the paper. Comparison between Self-adaptive Fuzzy controller based on scaling factor selfadjusting and conventional FC verifies the proposed control method.
