SINGLE PREDICTION PREDICTIVE CONTROL

The algorithm of Single prediction Predictive Control (SPC) is given. The equivalence between SPC and conventional Multi-prediction Predictive Control is discussed, and these two algorithms are well matched in control performance. Some necessary and/or sufficient conditions for the stability of closed loop SPC system are given on the basis of stability analysis, with the relative predictive gain as the tuning parameter of the closed loop system. The SPC algorithm based on the state space model is also given which made the calculation more simple. If the state variables are available, the ability of disturbance rejection of the closed loop system can be highly improved by state variable feedback.
