Operator based robust nonlinear control for a thermal process with input constraint

In this paper, operator-based robust nonlinear control is proposed for a Peltier actuated thermal process with input constraint. The Peltier actuated thermal process is a typical nonlinear affine system, where there exists an input constraint for the Peltier actuator and the maximum providing power is 30[W]. Moreover, the Peltier actuator and the temperature sensor are located at the different place in the cooling process such that some uncertainties are included in the estimating temperature at the actuated place by using support vector regression (SVR) based model. As a result, operator-based sliding mode nonlinear control considering input constraint is presented for the thermal process using Peltier device. Finally, simulation results are given to show the effectiveness of the proposed method.
