The paper present efficient Fault-tolerant Control approach using Interval Type-2 Takagi-Sugeno Fuzzy Controller (IT2TSFLC) with conventional Proportional Integral (PI) controller for MIMO hybrid nonlinear level process. The implementation of control algorithms for MIMO systems is challenging due to variations in dynamics because of changing in operating point and the characteristics of nonlinear dynamic interaction. Such difficulties often deteriorate the performance of industrial MIMO process. This work develops T-S modeling of MIMO hybrid level process thereafter designed FTC using combination of knowledge base IT2TSFLC controller and model base PI controller subject to actuator and system component faults. To verify the applicability of the proposed FTC, this work presents a Two Conical Tank Interacting Level System (TCTILS) to examine the control performance. Along with, simulation results of proposed scheme is compared with Type-1 Fuzzy Logic Controller (T1FLC) and PID controller. Simulation results show that the IT2TSFLC relies a good dynamic behaviour of the TCTILS, a perfect level tracking with no overshoot, lesser settling and rise time. Two different error indices Integral Absolute Error (IAE) and Integral Square Error (ISE) are used to validate the proposed FTC scheme among two other scheme. [ABSTRACT FROM AUTHOR] |
