Proportion integral differential generalized predictive control(PID-GPC), a new type of generalizedpredictive control(GPC) is introduced, and its quality is analyzed with internal model control (IMC). A veryimportant characteristic, which distinguishes GPC from ordinary IMC, and the robust effect are found. At thesame time, a robust region is obtained according to the control laws, so that the defect that the robust analysiscould be carried out only with stable models is overcome. It is verified that the robustness of PID-GPC is strongerthan general GPC.
