基于扰动预测的非线性过程收缩约束模型预测控制

A Contraction-constrained Model Predictive Control for Nonlinear Processes using Disturbance Forecasts

Ryan McCloy, Lai Wei, Jie Bao

摘要:

模型预测控制(MPC)已成为过程工业中应用最广泛的先进控制方法。在许多情况下,扰动的预报是可用的,例如,根据天气预报预测可再生能源发电量。虽然扰动的预测可能不准确,但利用这些信息可以显著提高响应于扰动的控制性能。通过利用过程和干扰模型,可以预测未来的系统行为,并用于通过最小化包含这些预测的经济代价函数来优化控制动作。然而,当过程是非线性的时,在这种方法中得到的闭环系统的稳定性保证通常是困难的。在下面的文章中提出的是一个收缩约束的预测控制器,优化过程的经济性,同时确保稳定的运行目标受到干扰的测量和预测。

英文摘要:

Model predictive control (MPC) has become the most widely used advanced control method in process industry. In many cases, forecasts of the disturbances are available, e.g., predicted renewable power generation based on weather forecast. While the predictions of disturbances may not be accurate, utilizing the information can significantly improve the control performance in response to the disturbances. By exploiting process and disturbance models, future system behaviour can be predicted and used to optimise control actions via minimisation of an economical cost function which incorporates these predictions. However, stability guarantee of the resulting closed-loop system is often difficult in this approach when the processes are nonlinear. Proposed in the following article is a contraction-constrained predictive controller which optimises process economy whilst ensuring stabilisation to operating targets subject to disturbance measurements and forecasts.
