As linear quadratic Gaussian (LQG)-based benchmark used in the economic performance evaluation algorithm is inaccessible, a new method based on model prediction control (MPC) structure evaluation benchmark is proposed for economic performance assessment. The algorithm uses the process model with simplified disturbance to design controller while the real process model is used to calculate the MPC performance curve with input and output variance constraints, based on which the economic performance evaluation optimization problem is built, and economic performance evaluation results are gotten based on the analysis of the optimization results. The proposed algorithm effectively avoids the calculation error caused by model, the simulation results show that the algorithm is more accessible.
