%X Smith predictor results in poor robust stability and steady-state error when it controls the integrator plus time delay process,and cannot be used in practice.To address the problem,a kind of double predictive PI (DPPI) controller for this process is proposed.The DPPI controller is of two kinds of predictive PI controllers,inner loop and outer loop predictive PI controller.The inner one stabilizes process,while the outer one eliminates the steady_state error and improves the control performance.The advantages of this controller include simple structure,few tuning parameters and easy tuning.The simulations and practical application show the good performance and robust stability of DPPI controller under model-process mismatching and disturbances.
