Modeling and Simulation for Inverter and Motor Based on Mixed Logical Dynamical Model
摘要
Abstract
Inverter circuit is a continuous state variable is driven by a discrete control signal with time evolution of a typical hybrid system,traditional modeling method based on mathematical model only consider the system either ignore discrete control change the state of continuous change of the system, and the ignored either considering only the system state of continuous change of discrete control system change, it is very easy to cause the loss of fault information is important, greatly influence the real-time performance and reliability of fault diagnosis. This paper has established the mixed logic dynamic model of inverter and motor through the analysis of the mode of the inverter and motor system, and using MATLAB/SIMULINK to simulation analysis the fault mode of inverter and motor, the simulation results shows that the method is very good to describe the output characteristics of system when inverter fault,provide accurate fault information for subsequent fault diagnosis.关键词
