摘　　要： 针对飞轮电池中非线性摩擦的特点,建立了基于Lugre动态摩擦模型的飞轮电池系统状态方程。设计了遗传算法优化的滑模控制器对飞轮电池中的动态摩擦进行补偿。仿真结果表明,该方案可以实时补偿系统中的动态摩擦,达到满意的补偿效果,获得较高的位置跟踪、速度跟踪性能和鲁棒性能。并且由于遗传算法的优化,减小了滑模控制器的抖振。 In order to deal with the nonlinear friction existed in the flywheel battery, a state function based on Lugre dynamic friction model of flywheel battery was established. A sliding mode controller optimized by genetic algorithm was designed to compensate dynamic friction of flywheel battery. The simulation results show that, this control strategy can compensate the dynamic friction and achieve satisfied performance, especially higher positioning tracking accuracy, higher velocity tracking accuracy and robustness, the chattering of slide mode controller is eliminated by the optimization of genetic algorithm.
