【摘要】 针对地铁转向架综合测试平台电液伺服系统的控制需要,提出了一种新型自适应遗传算法(GA),采用以基因为单位实施进化操作,利用基因间的距离控制基因的交叉与变异,补充相角裕度作为适应度的罚函数,保证了算法不陷入局部收敛,兼顾了系统的时域性能指标与鲁棒性统一．实验证明,由该GA算法获得的优化的电液伺服系统 PID控制参数,在实际应用上获得了满意结果．更多还原

【Abstract】 A kind of new GA is put forward, that caculated way satisfies the control demand of the metro bogie comprehensive test terrace electro-hydraulic servo system. The gene is adapted to carry out the evolution operation for the unit. Crossing with the average Euclid distance of the gene control gene with the variation. The phase margin is used as the function of penalty that one adaptive degree calculate. The calculate way is guaranteed not to sink into the part to refrain from rash action. The index sign of time domain and robustness of the system is considered to unify at the same time. The good result is through certificated: Being applied in the actual engineering by the electro-hydraulic servo system PID control parameter that based on the new SAGA to acquire excellent to turn.更多还原
