摘要本文提出了一种非保守鲁棒非线性模型预测控制方法,该方法能保证在不确定性条件下满足约束条件和最优期望性能。所提出的控制方案进行评估,通过模拟使用一个众所周知的基准问题,其中的半间歇式聚合反应器的操作进行了优化,在非常严格的温度公差限制。仿真结果表明,所提出的方案是能够优化过程操作,同时,它确保了鲁棒性的操作在整个范围内的不确定性。
Abstract In this paper, a non-conservative robust nonlinear model predictive control scheme that can guarantee satisfaction of the constraints and optimal expected performance under uncertainty is introduced. The proposed control scheme is evaluated by simulations using a well known benchmark problem where the operation of a semi-batch polymerization reactors is optimized under very tight temperature tolerance limits. The simulation results show that the proposed scheme is capable of optimizing the process operation and, at the same time, it ensures robust operation within the whole range of uncertainties.
