摘　　要：研究了一种采用脉冲调制器的空空导弹直/气复合控制系统设计方法及其稳定性。首先假设直接力是连续量,按照比例与气动舵进行混合,采用三回路设计方法得到混合后的控制量,之后采用脉冲调制器对得到的连续量进行调制,得到直接力装置的开关指令,最后采用非线性描述函数法分析控制系统的稳定性,在此基础上选取了合适的脉冲调制器参数,仿真结果表明了该方法的合理性。Based on pulse modulator,a method of lateral thrust and aerodynamic compound control system design in air-to-air missile and its stability are studied.First,the lateral thrust is assumped to be continuous and blended with aerodynamic fins accordding to a certain proportion,and the compound control is designed based on three-loop control method.Then the switch order of direct force device is obtained based on the pulse modulator.At last,the stability of control system is analysed based on describing function method,and then the parameter of pulse modulator is properly chosed.Simulation results show the validity of the proposed design.
