Output Predictive PI(OPPI) is a new method used in process control. The PI (Predictive PI) and OPPI methods are introduced briefly. A new OPPI method based on analysis of B spline is presented. This method analyses discrete curve and predicts output of the process controlled with three order B spline function, and carries out PI control with the predictive output. The results of its simulation and application used in tube typed furnace and constant temperature trough are given. It is simple,reliable, easy to realize, and is suitable for temperature control and other objects with slow time varying feature.
