超机动飞机动态逆-PID控制器设计

对超机动飞机在大迎角机动下的控制律进行设计,并完成相关仿真验证.通过引入推力矢量技术,建立带推力矢量的飞机非线性数学模型;采用奇异摄动理论,将飞机状态划分为快慢变换不同的同路,分别应用动态逆设计飞行控制律;并采用PID控制补偿由于未精确建模带来的系统逆误差;最后对所设计的控制律进行了机动指令飞行仿真.仿真结果表明,设计的控制律能在大迎角机动条件下控制飞机跟踪指令飞行,并保证闭环系统的稳定性.

Dynamic Inversion-PID Controller of a Supermaneuverable Aircraft

A technique which used to design the flight control system for a highly maneuverable aircraft was described,and the related simulation was finished.The nonlinear model of a maneuverable aircraft which with thrust vector control(TVC) was established.The singular perturbation theory was used to separate the dynamics into fast and slow sub-systems,the dynamic inversion theory was used to design the control laws of the two sub-systems separately,the PID control theory was used to compensate the system inversion...
