一种扁薄副翼全电舵机动态响应的仿真计算

Dynamic Response Simulation of a Flat and Thin Aileron Electromechanical Rudder

为了解决当代导弹很薄的翼型空间给副翼舵机机构布置带来的技术难题,文中提出了一种超薄舵机机构方案,并采用仿真计算的方法对方案的合理性进行了验证。文中建立了驱动机构、无刷直流电机、PID串联控制器等主要因素的数学模型,在Simulink中对模型进行了运算。计算结果表明,在舵机的测试工作点,带宽达到了10 Hz,舵机的稳态误差、扰动响应等主要性能指标均达到了设计要求,舵机系统具备了较强的位置指令跟踪和高动态响应能力。

In order to solve the technical problems caused by the thin airfoil space of contemporary missile to the aileron rudder installation, a scheme of ultra thin rudder mechanism is proposed in this paper. The reason- ability of this scheme is verified by simulation. The mathematical models of the driving mechanism, brushless DC motor and PID series controller are established in this paper, and the calculations on the models are car- ried out in Simulink. The results of the calculation show that the bandwidth of the rudder reaches 10 Hz at its testing point, the main performance indexes such as steady-state error and disturbance response of the rudder have met the design requirements, and the aileron rudder has good position tracking performance and high dy- namic response.
