Programmable controller is a general controller, which can input the program into the central processing unit through computer programming, and realize the automatic control of the equipment by using the established program. At present, the programmable controller combines the technology of machinery, communication, automation control and computer to control the equipment automatically, which has become

In this paper, an inversion controller is designed for the attitude of aircraft. 　　The simulation results show that the designed inversion controller is effective for controlling the stable flight of a Four-rotor aircraft. In order to improve the dynamic performance and stability of the aircraft better, the angle measurement deviation is taken into account in

Due to the influence of low-frequency resonance characteristics of stepper motors, the control efficiency and accuracy of the previously designed network dangerous data controller are low. Therefore, the subdivision controller of network dangerous data is designed. The current fluctuation will occur when the network data is transmitted to the stepper motor in the controller. The

Aiming at the problems of slow response and poor robustness of electric power steering system, the hardware structure of electric power steering system is designed, and a fuzzy control algorithm is proposed. The membership function of the fuzzy control algorithm is represented by Icon method, and the fuzzy theory set is planned. 　　Finally, the control
