Time-varying Modifying Factor Fuzzy Controller Based on the Minesweeping Strategy
Jingsong Hu, Jiabing Wang, Gui Wu Hu · 2008
By continuing the control surfaces of the time-varying modifying factor analytic expression method, a new algorithm is constructed to improve the properties of the fuzzy controller obviously. The algorithm has two merits: (a) static error is erased by fuzzy method; (b) operation speed is fast. The excellent quality control and rapid response real time system can be realized together. Furthermore, a new heuristic search strategy, called minesweeping strategy, is presented to optimize the fuzzy controller. The minesweeping strategy lets the current search "jump out", from the current local minimum by exploiting a new area that is far away from local minima obtained erenow. Therefore the strategy to solve local minimum problem is more successful and faster than other methods. The fuzzy system made by the two methods shows fine performances in simulating experiments.
