摘要: Abstract Two different approaches are investigated: (1) Model Predictive Control (MPC) utilizing a linear model resulting from local linearization of the plant at each time step; and (2) Feedback Linearization (FL) with MPC in an outer loop to avoid constraint violations by linearizing controller. In latter case constraints generally nonlinear optimization problem must be solved iterative manner. These two techniques compared terms their stability properties, on-line effort relative performance on practically motivated test examples.
