Abstract

Abstract: The intake pressure control system of the high altitude platform has the characteristics of large time delay. The controlled object is affected by uncertain factors such as input noise and phase delay, which leads to the problem that the control system is difficult to control accurately, and thus brings challenges to the design of the controller. To solve this problem, firstly, the measurement noise suppression based on Tracking Differentiator (TD) is used to estimate the system input noise, and the compensator is designed by introducing phase compensation based on tracking differentiator and Fal function filtering algorithm. Then, the measurement noise suppression algorithm of tracking differentiator is designed for the intake pressure control system of high altitude platform, and the filtering characteristics are analyzed. When designing the phase compensation method, not only the separation of random noise in the measurement signal is considered, but also the jitter signal in the differential signal is filtered, so that the system initial signal and the filtered smooth differential signal reconstitute a new useful signal, and finally solve the problem of the influence of the phase lag of the output signal on the control accuracy. Through numerical simulation, the classical fhan algorithm is compared with the proposed Fast + PA (Phase Advancer) algorithm, and the advantages of Fast + PA algorithm in noise suppression are verified. The results show that Fast + PA algorithm, through adjusting the important parameters filter factor h₀ and forward prediction compensation factor λ value, can not only eliminate chatter and ensure the efficiency of filtering, but also has good phase compensation and dynamic response ability..
