Simulation And Software Design Of Three-phase Synchronous Motor Servo System

With the rapid development of the servo system industry in China,the need to develop servo system application components for large-scale simulation systems and be able to output correct simulation results in accordance with the operating rules of actual servo systems has also gradually arisen.Taking a certain firepower control simulation system project as the background,this topic focuses on the modeling,simulation,and modular development of a certain anti-aircraft servo system.Because the project requires the use of C ++ for development,and does not allow the use of MATLAB to generate code to assist software development,it is necessary to use C ++to write the servo simulation module of the fire control simulation system according to its requirements.Therefore,in this paper,the modeling and simulation design of a certain anti-aircraft servo system is carried out.Taking the selection of the most suitable C ++ coding scheme as the guiding idea,the theoretical correctness and feasibility of two modeling and simulation strategies are introduced and explained step by step.Performance,advantages and disadvantages,and finally choose one of them,finally complete the software design work,and perform a series of software function tests on the software.First,the article introduces the background of the project,which is a fire control simulation system,describes its functional architecture,and analyzes the role of this topic in the system.Then,through the demand analysis of the subject and the introduction of related parameters,it lays the foundation for the subsequent modeling,simulation and software design of the servo system.In terms of theory,the article introduces the mathematical model of the three-phase permanent magnet synchronous motor in the natural coordinate system,two-phase rotating coordinate system,and two-phase stationary coordinate system,and the basic concepts of Clark transform and Park transform.The basic concepts of common vector control algorithms provide theoretical tools for modeling and simulation of servo systems later.Then,the article models and simulates the servo system of an antiaircraft artillery.Firstly,it analyzes the modeling and simulation strategies based on the transfer function,and elaborates the problems existing in the software design of the solution.Because this solution is not feasible in software design,the S-function-based servo system modeling and simulation strategy is derived.Taking into account the code reusability,coding complexity,maintainability,and scalability,it is finally determined that the Modeling and simulation strategies guide software design work.Finally,the article designs and codes the software modelling and simulation of the selected anti-aircraft servo system,including software requirements analysis,software outline design,and detailed implementation of the code,and finally completes the software function test,including the stage Jump,ramp signal,zero-crossing test and joint tuning test,verifying the reliability of the software function and the correctness of the modeling and simulation ideas.
