Abstract: In this paper, an operator-based fault detection method for actuator fault of an aluminium plate thermal process is proposed by using operator-based robust right coprime factorisation (RCF) approach. In details, operator-based output tracking and fault detection system design for single input single output (SISO) system is proposed, then the theoretical analysis is extended to multi input multi output (MIMO) system. Based on the proposed design schemes, the output tracking performance can be realised and the actuator fault can be detected. After developing a mathematical model of the three-input three-output aluminium plate thermal process, the proposed design schemes are applied and the effectiveness of that is confirmed by the simulation results.

Keywords: operator-based robust FCF; right coprime factorisation; fault detection; thermal processes; actuators; aluminium plate; SISO systems; MIMO systems; output tracking; actuator faults; mathematical modelling; simulation; tracking performance.
