| Abstract: | Aiming at the characteristic of time delay in control process,the predictive control algorithm based on time domain response characteristics is provided.The algorithm predicts the future output by using current and previous sampling information as well as the control information has been output,thus makes the control signal without deviation and obtains optimal control performance indexes.The feasibility of this algorithm is verified by theoretical analysis and Matlab simulation.The algorithm features simple calculation,good robustness,high anti-interference capability and excellent tracking performance,it offers ideal control effects for first order large time delay systems. |
