By proposing the multi-step control set and using it as the terminal set,a new design method of robust model predictive control(MPC) is presented for the constrained polyhedral uncertain systems.Through designing a series of feedback control laws,the new robust controller can achieve large feasible region and high control performance.The characteristic property of the multi-step control set also makes it possible to derive an algorithm with low online computation burden.It could make a good trade off among the initial feasible region,the control performance,and the online computation burden.The numerical examples verify these results.
