对于具有非线性、时变和强耦合特性的动力伞系统,采用常规控制方法难以获得满意的控制效果,而采用神经网络与传统PID相结合作为控制器,使得所设计控制器能够针对非线性、时变的气动特性自适应地调整控制参数,实现对PID控制器参数的寻优整定,简化了设计过程。利用Matlab软件对系统进行仿真,给出了相应的仿真结果。
For the dynamic parachute system with nonlinear, time-varying and strong coupling characteristics, it is difficult to obtain the satisfactory control effect by using the conventional control method. The neural network and the traditional PID are used as the controller, so that the designed controller can be applied to the nonlinear, The time-varying aerodynamic characteristics adaptively adjust the control parameters to achieve optimal tuning of PID controller parameters, simplifying the design process. Using Matlab software to simulate the system, the corresponding simulation results are given.
