Abstract: The neural network with BP algorithm has these disadvantages, such as slow
convergence rate, long learn time, local optimization and random value for the initial weight of the net, although it has been widely applied to regulate the parameters of PID controller. A new type of controller called PIDNN, which coalesces traditional PID and neural network together, is introduced in this paper. It overcomes these shortcomings mentioned and has better robustness. Then it is used in the flight control system of UAV, the simulation results show that it improves the performance of the system effectively.
