Artillery Servo System Based On Fuzzy Adaptive PID Control Design

This paper aims to improve the system in a large inertia, large lag and stability in harsh environments, accuracy and fast performance for intelligent existing artillery servo system improvements.The main content of the paper first integration of the various advantages of fuzzy control and classical control theory, the researchers designed a fuzzy adaptive PID controller, to suppress the disturbance of the system and the plant model uncertainty, it allows the artillery servo system in the harsh environment of the battlefield through online identification function automatically corrects system parameter values to achieve rapid response control requirements, improve shooting accuracy, while ensuring system stability.Then, on this basis, the key part of the design of the system hardware elaborate, including analysis of the overall structure of the servo system, the structural characteristics of TMS320LF2407DSP as the core controller and its control performance, the characteristics of the implementing agencies of permanent magnet synchronous motor, and space vector pulse width modulation technique to achieve as well as the selection of the sensing element.Then, after the the introduction development environment CCS system program using C language to write and debug. Distinguish module program subroutine called by the main program to achieve the function of each module, at the same time rendering system is given a flowchart of the operation of the main program and the interrupt subroutine.Finally, the simulation software MATLAB are introduced, using simulation software servo control system based on fuzzy adaptive PID controller, and by comparative analysis of the results of experimental simulation results with conventional PID controller.By the results of the simulation experiments show that the AC servo system based on fuzzy adaptive PID control algorithm design artillery has better control effect, can effectively adapt to the complex and ever-changing battlefield environment, the artillery of the technical indicators.
