Based On DSP Radar Servo Control System Research

With all kinds of new high-technology and control theory's development and progress, using the permanent magnet synchronous motor servo motor as the ac servo system, because of its many advantages,such as simple structure, control manufacturing outstanding performance, efficiency, high performance,and price cheap, It has been widely used in higher precision and speed control, wide range of servo system of speed required very high control field. Such as numerical control machine, special equipment, radar antenna, etc. In this paper, the TI company production motor control special DSP (digital signal processor) TMS320F2812as control core device, It designed a set of based on DSP radar servo control system, and the main contents are:First, It expounded the background and design meaning of the topic, the paper analysed the performance requirements of radar servo system. According to the request to establish servo system in different coordinate mathematical models, and It also design the total control scheme of the system, in view of the different parts of the plan to achieve the function, It determined the composition of the system's components.Second, It designed hardware and software of the control system, The hardware, focusing onthe structure and performance of the digital signal processor (DSP) F2812, is given based F2812as control core device hardware circuit diagram, the principles and functions of the circuit implementation are analyzed; The part of software, this paper introduced the software development environment CCS, gived system's main program and each interrupted the flow chart and operation procedure part program code.Third, the control strategy of this system are introduced, the vector control, the basic principle of thoughts and the control of vector control's five current control method were discussed,.Analyzing the voltage space vector control (SVPWM) process to realize the algorithm, this paper expounded the fuzzy control theory, and designed the fuzzy PID controller.Finally, the MATLAB/SILULINK software were introduced in this paper, the use of MATLAB simulation tools SIMULINK to the whole system modeling,'s simulation. Through the analysis of the simulation, the results verified the validity and feasibili-ty of the design scheme.
