Passive Approach for Fault Tolerant Controller Using Hybrid Controller Structure for Effective Level Control of Conical Tank System

The Article Propose An Efficacious Fault Tolerant Control (FTC) Strategy Using The Hybrid Controller Structure To Establish Stable And Tracking Control With Two Faults Constrain In The Area Of Two Tank Canonical Non-Interacting Level Control System (TTCNILCS). Many Process Industries Use Canonical Tanks Because Of Its Varying Cross-Section Area Which Contributes Better Throughput From An Outlet For Different Material. Hence TTCNILCS Exhibit Nonlinear Behavior Because Of Its Changing Cross Section Area. The Problem Of Passive FTC (PFTC) For The TTCNILCS With The Unknown Actuator And Sensor Fault Is Investigated. The Actuator And Sensor Fault Is Assumed To Have No Traditional Affine Appearance Of The System And Control Input. Hybrid Controller (Neural Network Plus PID Controller) Is Used To Design PFTC And Implement To Achieve Satisfactory Steady-State Performance From TTCNILCS. The Effectiveness Of The Proposed Controller Validate From The Simulation Results And Errors Like MSE, ISE And ITAE.
