Abstract: We propose in this paper an application of fractional-order PIλ controller as an alternative to solve some of the control problems that can arise. It aims to apply the analytical tuning procedure to control the heat flow systems. The system modeled by first order system involving time delay, this kind of systems whose closed-loop characteristic equation are fractional order quasi-polynomials. Using the proposed method, the entire stability region of PIλ controllers is obtained and visualized in the plane (Kp, Ki, λ). Simulation and experimental results on thermal system are given to show the effectiveness of this type of controllers and this tuning rule.
