【Abstract】 Based on fuzzy logic and variable structure control, a design scheme is developed for robot manipulators. The variable structure controller is employed as a supervisory controller to guarantee the state of the robot manipulator bounded. The fuzzy logic system is used to estimate the unknown part of the robot manipulator system. The control scheme utilizes an improved genetic algorithm to adjust the parameters of the fuzzy logic system, so that the output of the system can follow the desired trajectory. It can reduce the inherent chattering of the variable structure control. Simulation results show the effectiveness of the scheme.更多还原
