摘要 针对飞行仿真转台系统,提出了一种新型的前馈控制器的设计方法,并对时间常数τ给出了迭代算法。该控制器适用于数字非最小相位系统,且控制器的实现不需要指令信号的超前信息,校正后的系统在低频段相移近似为零,增益近似为1。以某飞行仿真转台系统为例进行了数字仿真,仿真结果表明了该控制器的有效性。 Forflightmotionsimulatorsystem ,anovelfeedforwardcontrolschemeisproposed .Thisproposedcon trollerisapplicabletonon minimalphasedigitalservosystem ,andthepreviewinformationofthedesiredoutputisnotneed ed .Byusingthiscontroller,theoverallsystem’sfrequencyresponseexhibitsasmallphaseerrorandgainerroratlowfre quencyrange.Simulationresultsforaflightmotionsimulatorsystemshowtheeffectivenessoftheproposedapproach .
