PSIM’s Digital Control module is a flexible, time-saving solution to analyze systems in z-domain and convert from analog to digital control.
Achieve more analysis with less cost
With higher performance and lower cost, microcontrollers/DSPs have been increasingly used in converter control in power supply and motor drive applications, requiring control algorithms to be implemented in the discrete time z-domain.
Unlike analog control, there are unique issues in digital control loop design, such as:
- Quantization and resolution
- Delay resulting from processor computation
As a result, a controller that works in the analog s-domain may not work in the digital z-domain.
Simulation and Power Conversion
Test in Simulation – Not production
PSIM’s Digital Control Module lets you implement the digital control algorithm with z-domain simulation blocks making it easy to check the performance and stability of a digital control loop. You can easily test the effects of quantization and observe the effects of digital delay on a control algorithm, allowing users to debug and troubleshoot in a simulation environment.
Smooth conversion from analog to digital control
To facilitate digital controller design, a utility tool is provided to convert an analog controller to a digital controller. After the controller is designed in analog s-domain taking into account the digital delay, the controller can be converted to a digital controller in z-domain and implemented directly in PSIM.
