Robust fault tolerant thermal control system design of an aluminum plate with Peltier device

In this paper, an operator based robust fault tolerant method for fault signal to the output part of an aluminum plate thermal process with nonlinear Peltier device in the presence of input constraints is proposed by using robust right coprime factorization approach. In details, after describing a mathematical model of the thermal process, an operator based robust fault tolerant control system is designed for this process with input constraints, the fault signal to the output part is analyzed using two sorts of operators. The effectiveness of the proposed design scheme is confirmed by simulation and experimental results on temperature control for the aluminum plate with nonlinear Peltier device.
