基于误差扩张的MRAC及其在单元机组中的应用

MRAC Expansion Based on the Error and Its Application in Power Unit

随着自动控制过程的复杂化,系统受到环境的影响容易产生参数漂移,进而传统的PID控制算法受到挑战。在这种新的形势下,自适应控制应运而生并显示了其强大的控制优势。总体来说自适应控制分为三大类:模型参考自适应控制,自校正控制及其他类型的自适应控制。其中,模型参考自适应控制因其历史最为久远,应用简单而受到广泛的关注。本文将一种基于误差扩张的MRAC应用于单元机组的协调控制。通过仿真实验可以看出,这种方法有良好的适应性。

With the automatic control of the complexity of the process, the system affected by the environment parameter drift-prone, and thus the traditional PID control algorithm being challenged. In this new situation, the adaptive control emerged and demonstrated its strong control advantage. Overall, adaptive control is divided into three categories： model reference adaptive control, self-tuning control and other types of adaptive control. Among them, the model reference adaptive control of its most ancient history, the application of simple and widespread concern. This article will expand based on error MRAC applied power unit coordinated control. Simulation results showed that this method has good adaptability.
