Abstract

The predictive control of nonlinear systems with time delay is widely used, such as electronic equipment, petrochemical, paper and other industries, will be used in the predictive control system or tools of nonlinear systems with time delay. Predictive control for nonlinear systems with higher efficiency and higher precision is always a hot research topic. In our daily life, the predictive control of nonlinear time-delay system can be seen everywhere, because compared with other control methods, it has the advantages of stable operation and higher control precision. The most important is that the predictive control of nonlinear time-delay system has a good advantage in delay control and other aspects. With the continuous innovation of automatic control technology and microelectronics technology, the present technical level lays a solid foundation and provides a solid theoretical basis for the realization of predictive control regulation control of nonlinear systems with time delay.

This design is mainly based on the predictive control system design and application of nonlinear time-delay system as the research background, using MATLAB simulation tools to build the corresponding simulation model. In this model, the module library of MATLAB software is used to establish the system simulation model of predictive control of nonlinear time-delay system in power system application. The simulation model is built by MATLAB simulation software, and the simulation results of predictive control of nonlinear time-delay system are analyzed. The predictive control adopted in this design is PID predictive control algorithm. After the simulation of the control system, it can be clearly seen that the predictive control system of nonlinear delay system has the characteristics of fast response, no overshoot, stable operation, and good performance in suppressing oscillation and divergence.
