Measure and DMC control of battery separator thickness uniformity

摘要

Usually, effects of a system under PID control with considerable time delay are not satisfied. However, model-based predictive control is an advanced control strategy that uses a move optimization method for achieving satisfactory closed-loop dynamic responses of complex systems. This paper describes a real time scheme that utilizes DMC algorithm to deal with a large pure time delay in process and adopts nuclear radiation to measure thickness of battery separator. The system has been designed and implemented in one of the battery separator plants of China. And the method of measure and control has wide applicability for similar continuous thin material process.
