Programmable Signal Generator (Three-Phase)
Discrete-time or continuous-time three-phase sinusoidal signal generator with programmable magnitude, phase, frequency, and overlapping harmonics
- Library:
Simscape / Electrical / Control / General Control
Description
The Programmable Signal Generator (Three-Phase) generates a three-phase sinusoidal signal with programmable magnitude, phase, and frequency over time. You can specify one or two harmonics that can be overlapped on the signal fundamental frequency.
You can switch between continuous and discrete implementations of the block by using the
Sample time parameter. To configure the block for continuous
time, set Sample time to 0. To configure the
block for discrete time, set Sample time to a positive, nonzero
value.
