为了提高大型客机飞行的安全性,使其能在大气紊流中平稳飞行,基于线性二次高斯/回路传输恢复(LQG/LTR)方法设计了大型客机飞/推综合控制器。LQG/LTR方法以分离原理为核心,通过设计一个卡尔曼滤波器和一个最优反馈控制器来实现系统输出精确跟踪参考输入,且满足性能指标J最小,常用来处理有随机噪声干扰情况下的状态反馈。以某大型客机为对象进行仿真验证,仿真结果表明,所设计的LQG/LTR大型客机飞/推综合控制器具有良好的控制效果,能够在大气紊流条件下提高飞行的安全性。
In order to improve the flight safety of large passenger aircraft so that it can fly smoothly in atmospheric turbulence, a large passenger aircraft fly / push integrated controller is designed based on LQG / LTR (Linear Quadratic Gaussian / Loop Transmission Restoration) method. The LQG / LTR method takes the principle of separation as the core. By designing a Kalman filter and an optimal feedback controller, the LQG / LTR method can accurately track the reference output of the system and satisfy the minimum performance index J, which is often used to deal with random noise interference Status feedback. The simulation results show that the LQG / LTR large-scale aircraft flight / push integrated controller has a good control effect and can improve the flight safety under atmospheric turbulence.
