Combined Integrating Control Based on Dynamic Optimization Estimation

摘要

In this paper, a new type of controller based on the combined integrating systems is proposed, which is called a combined integrating controller. The controller's current output is determined only by the current input and the average value of the controller's previous output. The innovation is to introduce a time-delay positive feedback in the controller. The memory characteristics of the time-delay term keep accumulating error information and repeatedly learning so that the system can stably track and restrain any input signal without error. Simultaneously, the combined integrating controller is applied to conventional process systems based on dynamic optimization estimation in the case study to show absolute superiority over the nonpredictive control method (such as the classical PID control method).
