| The design and realiazation of a simulation-based development software platform for induction motor Variable Frequency Speed Regulation system(VFSR), where Visual C++6.0is used as the front development tool and MATLAB R2008a is the back simulation engine, is introduced in this dissertation. The design idea and general structure of the platform, as well as the system simulation, software programming and the designing of Human-Machine interface of the platform, are presented.Firstly, based on the stable/dynamic mathematical model of induction motors, the simulation models of V/F Control VFSR system, Vector Control VFSR system and Direct Torque Control VFSR system, are established respectively, and the corresponding simulation with MATLAB has been completed. The details of the main module of the established simulation models are provided in in this dissertation.Secondly, the fault condition of VFSR is focused on:the mathematical model is deduced based on switch-symbol-function and the corresponding simulation model is also built up, as paves the way to simulate and fault-tollerance design of VFSR under fault operation.Finally, the Visual C++and Matlab blend programming method is discussed, and then applied to accomplish the development software platform for induction motor VFSR system, which has been demonstrated effective by a development case on a3kW induction motor VFSR system. |
