Standalone Perturbation Signal Generation

Generate perturbation signals for custom frequency response estimation applications

Simulink^® Control Design™ software enables you to generate standalone perturbation signals in Simulink for desktop simulations and hardware implementations with code generation. You can inject these signals into your plant models to collect and analyze response data, allowing you to perform custom offline or online frequency response estimation and identify plant characteristics. With the available blocks, you can generate pseudorandom binary sequence (PRBS), superimposed sinusoidal, and sequential sinusoidal perturbation signals. Additionally, the sinusoidal signal generator blocks allow you to generate three-phase sinusoidal perturbation signals to identify the frequency response of three-phase AC power systems.
