摘要
针对新一代歼击机,基于避障思想研究了一种边界保护控制方法。首先运用动态逆控制器对飞机进行稳定控制; 在此基础上利用避障思想生成关键飞行参数的安全边界, 并用参数在线调节的动态矩阵控制方法修正飞机的控制量, 确保飞机在安全边界内飞行; 最后将所设计的飞行控制系统用于新一代歼击机的机动飞行仿真。仿真结果证明了该边界保护控制系统的有效性。
Abstract
This paper describes an envelope protection control system using obstacle-avoidance method for the new generation fighter.Firstly, a dynamic inversion controller is used to stabilize the fighter.Obstacle avoidance boundary protection method is then developed to generate the security envelope of the key flight parameters.The Dynamic Matrix Control (DMC) adjusts its parameters online to modify the control variables of the fighter.The developed dynamic matrix control scheme can guarantee the fighter flying inside the security boundary.Simulations are provided for angle of attack, and the simulation results show that the designed flight control system is effective.
