Abstract
This paper addresses the issue of the regulation of the dehydration air temperature in a dryer. The classical optimization approach is used to solve the optimal control problem for this kind of system because the linearized mathematical model involves the delay state. However, the presence in the model of nonlinear uncertainties, which satisfy the matching condition, is a reason to apply the Lyapunov redesign approach. It gives robustness to the optimal linear control, improving the closed-loop performance. Furthermore, the optimal–robust control algorithm was tested in a dehydration process. This is the first time that the optimal and the proposed optimal–robust controller has been applied in a real-time process.
