摘要
为提高无人直升机定高飞行控制系统稳定性和快速性,通过建立无人直升机动力数学模型,在模型指导下调整控制器参数,提高闭环系统的控制性能,并用MATLAB完成系统仿真,通过性能评估与串联、反馈校正,提高系统性能指标,改善无人直升机定高飞行品质,该方法可有效减小建模工作量和难度,直观表现无人直升机的定高飞行控制过程.
In order to improve the stability and rapidity of fixed high unmanned helicopter flight con- trol system, the paper improves the control performance of the closed-loop system by establishing the dynamic mathematical model of unmanned helicopter and adjusts the parameters of the controller under the guidance, completes the simulation with MATLAB. Through the performance evaluation and series, feed-back correction,the system performance,and a quality improvement of unmanned helicopter fixed high flight are improved. This method can effectively reduce the modeling workload and difficulty, and intuitively express the process of unmanned helicopter fixed high flight.
