A cooperative co-evolutionary control method for Stewart platform

Considering the nonlinearity and strong coupling of Stewart platform, a co-evolutionary control method is proposed for it, based on this method, ¿ distribution function is introduced to regulate the probabilities of individuals production to promote the speed of evolutionary according to the characteristic of control system. Compared with the traditional genetic algorithm, the searching space has been decreased greatly by the method. Furthermore, tested on Stewart platform, the control mode in this paper has the traits of high-speed response, small overshoot and better robustness so on.
