Centralised neuro controller for two conical tank interacting level system

摘要

The implementation of control algorithms for MIMO systems is often complicated due to variations in process dynamics that occur because of changes in operating point and the characteristics of non linear dynamic coupling. Such changes often render the performance of existing decoupled based decentralized fixed gain PID and Gain scheduling PID controllers unsatisfactory. The dynamic uncertainty associated with MIMO systems make existing model based decoupling impractical for real time system. This work presents control of non linear Two Conical Tank Interacting Level System (TCTILS) using centralised Neuro controller. The TCTILS is considered as two tank benchmark problem used by many researchers. Simulation results show that the centralised Neuro controller realise a good dynamic behaviour of the TCTILS, a perfect level tracking with lesser overshoot, lesser settling time, reduced interaction and good rejection of external load disturbances.
