✦ Synopsis

After having briefly portrayed the basic principles of predictive control, three adaptive predictive control algorithms-the GPC algorithm and two new modifications of it proposed by the authors, called the MGPC (modified GPC) algorithm and the DGPC (direct GPC) algorithm-will be discussed. The main disadvantage of the GPC algorithm, namely the noise sensitivity, will be highlighted, when the real-time application to a plant with variable dead-time, a shaker conveyor system for transportation of plastic beads, will be studied. Both new algorithms proposed here show good behaviour in reducing the computational burden and achieving a better disturbance rejection than the direct application of the GPC algorithm.

After a short description of a turbogenerator plant, some of the most important general aspects for adaptive predictive control schemes are introduced. Four different adaptive predictive schemes, the DMC, GPC, VGPC and DGPC algorithms, are selected for real-time application at the turbogenerator pla
