Temperature Control Method of Humidifier Pipeline Based on Multi Model Scheduling Smith Prediction Algorithm
The pipeline temperature control of medical humidifier is a nonlinear variable structure system with hysteresis,large inertia and model parameters changing with flow,and it is difficult to use a single structure control algorithm to achieve high-quality dynamic control performance.Aiming at this problem,a Smith estimation control method based on multi-model structure scheduling is proposed,which adopts the model scheduling method at the flow balance point for controller design.Experimental tests prove that the Smith pre-estimation method of multi-model scheduling is suitable for pipeline temperature control with different set temperatures in different flow modes,which improves the dynamic performance and robustness of the control system.
