An optmi al param eter group w as obtained t roug m in mi ization, by w ic t e optmi al transm it func tion of electro ydraulic position servo system w as deduced. T en t e optmi al control of electro ydrau lic position servo system w as ob tained. T e con trasted analysis on t e dynam ic c aracteristic of electro ydrau lic position servo system before and after optmi um w as obtained t roug num erical em aciation. T e analysis result s ow s t at optmi al control can decrease t e surpass capacity of t e system and mi prove its respond.
