Transformation Module

In this paper, we explore a simulation model for induction motors comprising multiple modules. The transformation module serves as the core component, containing two primary functions: first, converting two-phase currents to three-phase currents in the coordinate system using inverse transformation rules; second, deriving rotor angular displacement through indirect vector control. The calculation formula for rotor angular displacement is as follows:

Additionally, our simulation model incorporates several submodules including the hysteresis current controller module, voltage source inverter module, induction motor module, current feedback module, and speed controller module. Notably, the induction motor module is constructed based on AC motor circuit equations, torque equations, and motion equations, forming a three-input, six-output subsystem. The inputs consist of stator voltages in the coordinate system, while outputs include rotor currents and rotor flux linkages in the coordinate system, along with output torque. Through this simulation model, we can gain deeper insights into induction motor operational principles and achieve more precise control implementations.
