Fermenter Temperature Control Based on LSSVM and MPC

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.
