چکیده

This paper presents a globally optimal nonlinear Model Predictive Control (NMPC) algorithm. Utilizing local techniques on nonlinear nonconvex problems leaves one susceptible to suboptimal solutions. In complex problems, local solver reliability is difficult to predict and often highly dependent upon the choice of initial guess. For the purpose of NMPC, local solvers can cause the algorithm to fail. Implementing a global solution technique (Falk and Soland [1969], Horst and Tuy [1990]), which guarantees global optimality, restores the integrity of NMPC technology. Due to the combinatorial nature of nonconvex optimization, real-time considerations must be considered. The proposed algorithm’s capabilities are demonstrated by the application of the controller on the benchmark control problem of the isothermal operation of a continuous stirred tank reactor (CSTR) with Van de Vusse reactions (Kremling and Allgöwer [1993]).

Hybrid model predictive control of a nonlinear three-tank system based on the proposed compact form of piecewise affine model

In this paper, a predictive control based on the proposed hybrid model is designed to control the fluid height in a three-tank system with nonlinear dynamics whose operating mode depends on the instantaneous amount of system states. The use of nonlinear hybrid model in predictive control leads to a problem of mixed integer nonlinear programming (MINLP) which is very complex and time consuming t...

Improved Optimization Process for Nonlinear Model Predictive Control of PMSM

Model-based predictive control (MPC) is one of the most efficient techniques that is widely used in industrial applications. In such controllers, increasing the prediction horizon results in better selection of the optimal control signal sequence. On the other hand, increasing the prediction horizon increase the computational time of the optimization process which make it impossible to be imple...
