PERFORMANCE INDEX BASED COMPARATIVE STUDY AND ANALYSIS OF HIGHLY COMPLEX NONLINEAR DYNAMIC SYSTEM

This paper presents the modification of adaptive neuro fuzzy interference system for interaction problem solving of highly complex nonlinear multiple input multiple output quadruple tank system. one of the problem of the mimo system is interaction which create major issues in industrial process. Major problem of industrial nonlinear process to control and stabilizes the dynamic response of the system. in this research paper gives Conventional PID controller and ANFIS based controller and also a modification of the ANFIS controller (CANFIS) for improving the dynamic response and change the coupling effect. The result of all controller for QTS system, CANFIS controller gives the better control and improve the dymamic response of the highly nonlinear control system. Based on performance criteria give better output than other controller and control and stabilizes the highly complex nonlinear system. ANFIS and CANFIS controller, which is used for nonlinear applications. Finally a comparative study of performance index and analysis between different control strategies is carried out.
