Abstract: In order to deal with the continuous-time systems in the industrial processes, a novel continuous subspace predictive control method is proposed. Firstly, it is developed by reformulating the continuous-time systems using Laguerre filters to obtain the subspace prediction output. Next, the subspace predictors are derived by QR decomposition from input-output and Laguerre matrix. They are then used to construct the incremental future prediction output and the continuous subspace predictive controller is designed. Finally, the process control simulations of an industrial evaporator system show the effectiveness of the proposed method.
