Can PSIM simulate digital control scheme?
Yes. The Digital Control Module in PSIM provides a number of function blocks, such as zero-order hold, unit delay, z-domain transfer function blocks, digital FIR and IIR filters, circular buffer, quantization block, and other blocks, which can be used to implement a digital control scheme. Further, an AC sweep with digital elements can be performed of a topology to determine the impacts of digital delay on the phase of plant response. This information is invaluable when implementing a control scheme in the z-domain. With PSIM one can study the effect of different sampling rates, investigate the quantization effect of the A/D conversion with different number of bits, and evaluate the performance of a digital filter. PSIM provides in depth support for digital control applications with the following modules:
The SimCoder + targets allow a control algorithm to be automatically converted into C code that is ready to run on a target DSP – F2833x, F2803x, F2802x, F2806x, F2837x, and F29004x. The Processor-In-the-Loop, PIL, module allows you to run your control scheme on a TI MCU while it controls your power stage defined in PSIM.
