Abstract
Three-phase inverter based on model predictive control is widely used, such as electronic equipment, power system, industrial and other industries, will be used in the three-phase inverter system or tools based on model predictive control. Higher efficiency and higher accuracy of three-phase inverter based on model predictive control is always a research hotspot. In our daily life, three-phase inverter based on model predictive control can be seen everywhere, because compared with other control methods, it has the advantages of stable operation and higher control accuracy. The most important is three-phase inverter based on model predictive control has good advantages in grid-connected control and other aspects. With the continuous innovation of automatic control technology and microelectronics technology, the current technical level for the realization of model predictive control based on three-phase inverter regulation control to lay a solid foundation, provide a solid theoretical basis.
This design mainly based on model predictive control three-phase inverter control system design and application as the research background, using MATLAB simulation tools to build the corresponding simulation model. The model uses the module library of MATLAB software to establish the system simulation model of three-phase inverter based on model predictive control in power system application. The simulation model is built by MATLAB simulation software, and the simulation results of three-phase inverter based on model predictive control are analyzed. The predictive control adopted in this design is PID predictive control algorithm. After the simulation of the control system, it can be obviously seen that the three-phase inverter control system based on model predictive control has the characteristics of fast response, no overshoot, stable operation, and good performance in suppressing shock and divergence.
