【摘要】 分析了线性二次型最优控制不适用于电液伺服主动抗振系统的原因，并根据电液伺服抗振系统特点，提出了以伺服阀p－Q特性为不等式约束条件的瞬时最优控制方法，抗振模拟试验结果证实了这一控制思想的正确性和有效性．更多还原

【Abstract】 The causes why the optimal control with lineal quadratic regulator is not suitabe for the electrohydraulic servo active anti - vibration system are analyzed. Based on Ihe charateristics of the electrohydraulic servo system, the transient optimal control method using the p - Q chaseter of servo valve as constheint condition of inequality is presented. The results of simulated tests have confirmed that this control method is correct and effective.更多还原
