MPC控制器的性能监视

Performance Monitoring for Model Predictive Controllers

本文介绍了MPC控制器的一种性能指标。该指标以MPC控制器在滚动优化中预计达到的稳态目标作为评估基准,没有苛刻的假设条件,且易于现场实时获得。以Honey鄄well公司的RMPCT多变量控制器为例,就干扰、模型误差等对性能指标的影响进行了仿真实验。

In this paper, a new performance index is introduced . It is based on the comparison of the achieved and designed objective functions. So it is free of any restrictive assumptions and can be calculated online with little effort. This index has been shown to be sensitive to disturbances and model mismatch through simulation examples using RMPCT controllers.
