Description

technical field [0001] The invention belongs to the scope of motor simulators, in particular to a multi-source signal processing system with networking expansion capability applied to motor simulators. Background technique [0002] The evaluation of motor controllers and control algorithms usually uses actual motors with loading and measurement equipment for experiments. This method has many shortcomings, such as: motor design, processing and preparation of supporting equipment take a long time and high cost; Change the motor parameters to achieve a comprehensive test of the motor controller and control algorithm; it is difficult to simulate the fault state of the motor. [0003] If the motor model can be analyzed with a high-performance processor, the real motor control signal can be replaced with an equivalent control signal, and the power output of the motor can be simulated in real time with a power electronic load, then a power-level motor simulator can be formed.
