Switch Approach of Control Zone and Optimization Zone for Economic Model Predictive Control
AbstractThe coordination of control and optimization is proposed for economic model predictive control in the paper. The characteristic is explained briefly with the field theory. The solution of economic model predictive control is gradient descent method. However, economic constraint condition makes the response too long. In order to improve the performance and save respond time, control and optimization should be considered separately in controller. The method is built for coordinating control and optimization, which separate the whole zone into control zone and optimization zone and switch in different zone. The respond time is reduced in control zone, and economic benefit is improved in optimization zone. Rapid response and economic optimization are obtained. The test and verification are made by the case study of Shell Standard Control Problem.
