This paper research on the working quality of the payload of a stratospheric airship at high altitudes. When the stratospheric airship working on the stratosphere, it is confronted with many complicated factors. Taking the stable platform equipped with the airship as the research object, combining Kalman filter and fuzzy pid control algorithm, we propose the algorithm which named fuzzy pid control algorithm based on Kalman filter. Simulink simulation results show that the proposed algorithm not only has the advantages of fast response, small overshoot, high control precision, but also can effectively restrain the interference in the environment, which make the stratospheric airship stability.

Semi active hydro-pneumatic suspension can improve the road support and ride comfort of the suspension system while considering manufacturing costs. Single chamber hydro-pneumatic suspension can achieve the purpose of adjusting damping force by adjusting the volume of hydro-pneumatic, and can reliably control semi-active suspension systems in practical engineering. This article first establishes a nonlinear mathematical model of a single chamber hydro-pneumatic suspension, and uses the designed fuzzy pid control to control the single chamber hydro-pneumatic suspension system. It was found that due to the dependence on expert experience in fuzzy pid control, the control effect is not significant. To improve the control effect,genetic algorithm is used to optimize the fuzzy pid correction coefficient and quantization factor, and control the single chamber hydro-pneumatic suspension. The dynamic simulation software Matlab/Simulink is applied for simulation. The simulation results show that when the simulated vehicle is driving on a D-level road at a speed of 12.5m/s, the semi-active hydro-pneumatic suspension under fuzzy pid control after genetic optimization is superior to traditional passive hydro-pneumatic suspension in attenuating vehicle vibration and improving vehicle smoothness.

According to the characteristics of the industrial production control system with multiparameters, nonlinear, lager time delay, an on-line parameter Adaptive fuzzy logical fuzzy-pid controller was put forward. This paper introduces the basic idea of pid and fuzzy-pid control, the application of the fuzzy-pid controller. The industrial process of liquid mixing is characterized by high nonlinearity, large time delay and multi-parameters. An on-line controller based on adaptive fuzzy logical fuzzy-pid was therefore designed. Then, the two simulation curves of conventional pid algorithm and fuzzy-pid algorithm were compared with each other, and the results showed that the fuzzy-pid control algorithm has a performance of shorter response time, smaller overshoot, better robustness and good stability. It is concluded that the designed fuzzy pid controller is reasonable to improve the control effect, implemented the online self-adaptive adjustment of the liquid mixing parameters.

Quadruped robot driven by high power density hydraulic device works in unstructured en- vironment. With variable load and various external disturbance, the hydraulic servo system has fea- tures such as nonlinear, time-varying parameters. Traditional control method has some limitation. In order to help the hydraulic servo system of the quadruped robot to adapt to harsh environments, and to obtain high control quality and control precision, an incremental fuzzy adaptive pid controller based on position feedback is designed to solve the related technical problems. Matlab/Simulink sim- ulation and experimental results show that the incremental fuzzy adaptive pid controller improves the dynamic performance of the system, enhances the respond speed and precision of the hydraulic ser- vo system, and has some theory significance and practical value.

In order to improve the yaw stability of the vehicle with active front steering system, an adaptive pid-type fuzzy control scheme is designed to make the yaw rate tracking the desired values as close as possible. A 2-DOF vehicle model with active front steering is built firstly, and then the fuzzy pid controller is designed in detail. The simulation investigations of the yaw stability with different steering ma- neuvers are performed. The simulation results show the effectiveness of the fuzzy pid controller for improving the vehicle＇s yaw stability.

In this paper, the speed loop and current loop controllers in vector control system are improved by using fuzzy control theory with parameter self-tuning function. The vector control system model of permanent magnet synchronous motor（PMSM） is established in MATLAB/Simulink environment. The speed control of PMSM under starting and sudden load is simulated. Comparing the performance of traditional pid control and fuzzy pid control, the results show that fuzzy pid control perfectly combines the accuracy of pid control with the dynamic characteristics of fuzzy control.
