In this paper, an adaptive temperature controller for the plastic extrusion process is designed. The proposed controller aims to solve the set-point regulation problem and the temperature trajectory tracking of a plastic extrusion process. The controller is an adaptive version of the First Sliding Mode Control which is robust towards parametric uncertainties and external disturbances. Also, the finite time convergence is demonstrated by Lyapunov arguments. Finally, the effectiveness of the proposed controller under several scenarios is demonstrated by computer simulations.
