[Abstract]:The guidance flight control system is the core and key part of the aircraft system. Its performance largely determines the flight performance and flight quality of the aircraft, especially the guidance accuracy. In this paper, the hardware design of the servo control system for a new type of all-digital target projectile electric steering gear is studied. The system adopts the high performance digital signal processor (DSP) and the pulse width modulation (PWM) technology to control the operation of four brushless DC motors (BLDCM). Firstly, on the basis of analyzing the working principle of the target missile control system, the function and framework of the attitude control system are analyzed and discussed in detail. At the same time, according to the performance requirements of the system, the components required for the system are selected. The control technology and PID control strategy of the target missile control system are studied emphatically. Finally, the overall design scheme of four independent servo control systems of steering gear controlled by DSP is presented. The main task of this paper is to design a set of hardware circuit matching with software for the guidance control system. The minimum system and external auxiliary circuit based on DSP, power supply circuit, servo drive circuit of steering gear, real-time deflection position detection of rudder surface and AD sampling and conditioning circuit, battery voltage detection circuit, rudder zero position detection circuit and so on are designed in detail. Finally, according to the performance of the system and the actual debugging results of the circuit for some anti-interference treatment. The last two chapters mainly do some simulation and analysis experiments on guidance control, mainly the test of hardware module and the combination of hardware and software. Then through three ground hardware-in-the-loop integrated simulation experiments, the software and hardware of the system are adjusted, including triaxial angle platform experiment, yaw distance test experiment and steering gear program control experiment. Finally, the problems and errors found in the simulation process are optimized and handled in time. Through the analysis and verification of the actual data obtained in the course of simulation test, it is proved that the hardware design of the system can cooperate with the stable and reliable work of the software, and at the same time meet the expected performance indexes.
