Feasibility and soft constraint of steady state target calculation layer in LP-MPC and QP-MPC cascade control systems

This paper mainly focus on the feasibility and soft constraint of steady state target calculation, which is one of inherent problem of predictive control. By using two-stage method, the state target calculation can be solved effectively. To guarantee the existence of feasibility domain, weighting and priority policies are presented to determine the feasibility and adjust soft constraints. Simulation results validate the effectiveness of the proposed approach.
