PSIM User Manual (Powersim Technologies Inc.)

(BQ) This manual covers both PSIM* and its add-on Motor Drive Module and Digital Control Module. Functions and features for these two modules are marked wherever they occur. The Motor Drive Module has built-in machine models and mechanical load models for drive system studies. The Digital Control Module, on the other hand, provides discrete elements such as zero-order hold, z-domain ransfer function blocks, quantization blocks, for digital control analysis.
