Exponential Arx Model Based Generalized Predictive Control for Thermal Power Plants
نویسندگان
چکیده
For nonlinear thermal power plants whose dynamics vary with load demand, a load-dependent exponential ARX (Exp-ARX) model which can exactly describes the nonlinear properties of the plants is presented. The Exp-ARX model requires only off-line identification. Based on the model, a constrained multivariable generalized predictive control (CMGPC) strategy is designed and implemented in a simulation of 375 MW thermal power plants. This CMGPC algorithm do not resort to on-line parameter estimation and can exactly predict the future outputs of the nonlinear plants, so it shown far better realizability and control performance than the usual GPC algorithm.

A nonlinear exponential ARX model-based multivariable generalized predictive control strategy for thermal power plants
This paper presents a modeling and control method for thermal power plants having nonlinear dynamics varying with load. First a load-dependent exponential ARX (Exp-ARX) model that can effectively describe the plant nonlinear properties and requires only off-line identification is presented. The model is then used to establish a constrained multivariate multi-step predictive control (ExpMPC) str...
متن کاملThe Rbf-arx Model Based Modeling and Predictive Control for a Class of Nonlinear Processes
This paper considers modeling and control problems of the non-stationary nonlinear processes whose dynamics depends on the working point. A hybrid RBF-ARX model-based predictive control (MPC) strategy without resorting to on-line parameter estimation for this kind of processes is presented. The RBF-ARX model is composed of the RBF networks and a rather general form of ARX model, which is identi...
متن کاملRBF-ARX model-based nonlinear system modeling and predictive control with application to a NOx decomposition process
This paper considers the modeling and control problem for nonstationary nonlinear systems whose dynamic characteristics depend on time-varying working-points and may be locally linearized. It is proposed to describe the system behavior by the RBFARX model, which is an ARX model with Gaussian radial basis function (RBF) network-style coefficients depending on the working-points of a system. The ...
