Abstract
Predictive control systems can significantly reduce the cost of setting up and developing converters. Currently, existing methods for implementing control systems have shown their effectiveness. However, some problems, such as ease of design and configuration of the device, and resistance to changes in load parameters, still require searching for new approaches to implement predictive control systems. This paper presents a new method for modifying the predictive control system model for DC-DC boost converters. The developed control system, in addition to the function of maintaining the required level of output voltage, optimizes the operation of the device to achieve maximum efficiency. It is shown that the output voltage level is regulated by changing the duty cycle of the control signal; and the efficiency of the device, by changing the operating period. It is established that a modified system for calculating the objective function allows using a sufficiently large planning horizon due to the reduction in the required computing power. The presented simulation results demonstrate the advantages of the proposed control method, including a fast transient response and a high degree of robustness.
