Abstract

Aiming at fermenter temperature control, a novel control scheme based on least squares support vector machine (LSSVM) and model predictive control (MPC) is proposed. Existent PID control doesn´t consider the model of controlled object, so it tends to bring steady-state error. So the proposed method utilizes LSSVM to obtain fermenter temperature´s model and then uses it to implement MPC. The simulation results show that the proposed method has better control performance than PID control.
