Title Model Analysis and Simulation of Induction Motor

Abstract At present, the rapid development of modern speed control system, induction motor with its simple structure, cheap price, manufacturing process, has a wide range of application。 This paper uses three-phase induction motor as the research object, gives the induction motor mathematical model of three-phase and two-phase coordinate system, explains the principle of the vector control and establishes the simulation diagram of induction model based of vector control。 The simulation results show that the motor’s performance of speed control is good。

Based on the simulation model of induction motor, the fuzzy control technology is applied to the control of the induction motor, and the simulation results are compared with the conventional PID controller by the design of speed fuzzy controller。

MATLAB comes with a graphical user interface (GUI)。 this paper based on the GUI, designs the induction motor model simulation interface, through the interface to facilitate the adjustment of the controller PID parameters to change the controller's output response。

Finally, the paper puts forward the synchronous control of mufti induction motor。 According to the principle of synchronous control, a model of two induction motor synchronization control is established, and the actual speed of the induction motor is the same as the setting speed of the induction motor。

Keywords: Induction Motor Fuzzy Control Graphical User Interface (GUI) Synchronization Control
