Real-time optimum control design using Maple Non-Linear Model Predictive Control Design

While deriving the optimal solution and performing feedback control in real-time is regarded as difficult to do realistically, using a high-speed solution known as the 鼎/GMRES method・which combines the continuous deformation method with the GMRES, real-time control has become possible.
