Discrete Active Disturbance Rejection Control for Chemical Processes

摘要

In this paper the discrete active disturbance rejection control (DADRC) is applied to two chemical process problems. In the DADRC framework, the external disturbances and internal dynamics associated with chemical processes are treated as the generalized disturbance to be estimated and compensated for in real time. The current discrete extended state observer is employed for estimating the generalized disturbance and therefore improves the performance of the closed-loop system.
