| Abstract: | A multi-input-multi-output (MIMO) controller was proposed to control a single-duct VAV system with a model predictive control (MPC) strategy. The structure of an internal model was built by analyzing the working mechanism and the dynamics of the system. The parameters of the model were found by experiment. MPC solved a constrained convex quadratic optimization by defining reference trajectories, constraint limits, prediction horizon, control horizon and weighting matrices. Simulation results and control for the actual system demonstrate the validity of the approach proposed. |
