This paper proposes a linear quadratic regulation(LQR)tracking control method based on a radial basis function(RBF)that successfully compensates for the shortcomings of the LQR method.

The LQR method depends on the linearity of a model.Specifically,an RBF neural network is used to approximate and compensate for the nonlinear part of a controlled object in the PID type-I,type-II and type-III control loops to improve the performance of the system.

Through the simulation of different industrial systems,such as underdamped,overdamped and critically damped systems,the method significantly improves the dynamic response performance indices,such as the rise time and settling time,of the system.
