The Design And Application Of Modern Air Defense Artillery Servo System

The recent wars give us a conclusion that the weapons technology in today's world has a high degree of automation, and is developing rapidly towards the direction of intelligent. The fire and command control system, whether they are airborne, ship, or on the ground was obedient to the total trend, implementing the principles, concepts, and the actual products constantly upgrade.Anti-aircraft gun servo system is the core part of the anti-aircraft gun weapon system, the merits of the servo system performance will directly affect the overall combat effect of air defense weapon system. In order to improve their own comprehensive combat ability of anti-aircraft gun weapon system and form the most effective weapon system, must make the servo system with high speed, high precision, high reliability and strong anti-jamming capability. So to stuy the affect of anti-aircraft gun servo system to the performance of fire control system is very important.In recent years, permanent magnet synchronous motor with its simple structure, high efficiency, high power factor and low inertia caused widespread concern in motion control, and applied to Navigation systems, radar antennas, CNC machine tools, robots, etc. However, the permanent magnet synchronous motor is a typical nonlinear, multivariable, strong coupling system, and by the motor parameter variations and external load disturbance uncertainties and other factors, to get a high-performance permanent magnet synchronous motor servo control system, must study the advanced control strategies to overcome these uncertainties, the system has a strong anti-interference ability and adaptive ability. Firstly, the vector control theory of meticulous research, focusing on id=0 control and maximum torque current ratio (MTPA) control in-depth analysis and understanding. Secondly, the traditional method of vector control energy consumption is large, complicated and dynamic performance computing and poor, we propose a permanent magnet synchronous motor vector control method based on fuzzy control intelligent integrator. In this method, the static and dynamic performance optimization of control objectives, based on the traditional methods of vector control on fuzzy control theory, fuzzy control and optimization algorithms for solving online stator current, torque system under the same conditions to obtain the maximum, while the stator use Current minimum, effectively reducing the loss of the system. Finally, add intelligent integrator based in fuzzy controller MTPA in, and the timing of the introduction of the integral part of a detailed analysis. Introduction of intelligent integrator effectively eliminate the steady-state error of the system, and enhance the overall ability to regulate the fuzzy controller. Simulation results show that the studied PMSM based integrator of intelligent fuzzy control servo control system to solve the loss, the stator current calculation complicated issues such as the existence of traditional vector control, improved static and dynamic performance of the system and enhance the robustness of the system.To further verify the actual effect of the servo system, the paper type TMS320F2812 DSP as the core to build permanent magnet synchronous motor control system, and designed the interface circuit and signal detection circuit is connected with the DSP. Software designed by CCS system control software, and applied to a permanent magnet synchronous motor control system. Finally, the dual-drag experiment platform, the system control effect a series of experiments to verify the system.
