基于控制性能比较的非线性不对称系统预测控制
Predictive controller for nonlinear unsymmetrical systems based on control performance comparison
摘要
Abstract
Some nonlinear systems in production process always show unsymmetrical dynamic characteristics. Theoretical results for these systems, especially for its control are very limited compared with their common occurrence in industry. In this paper, state feedback predictive controller based on the positive/negative linear models was designed to handle the shortage of two separate PID controllers based on positive/negative linear models. At each step of the control law calculation, the positive/negative controllers calculated each control action. The ultimate control action was determined by the comparison of control performance index of the positive/negative controllers. Simulation of pH control showed better control performance than two separate PID controllers.关键词
