Compute mean value of signal
Control and Measurements/Measurements
The Mean block computes the mean value of the input signal. The mean value is computed over a running average window of one cycle of the specified fundamental frequency:
As this block uses a running average window, one cycle of simulation must complete before the output gives the correct value. For the first cycle of simulation, the output is held constant to the specified initial input value.
Specify the fundamental frequency, in hertz. This value determines
the period (1/F) of the running average window.
Specify the input value for the first cycle of simulation. Default
Specify the sample time of the block, in seconds. Set to
implement a continuous block. Default is
|Sample Time||Specified in the Sample Time parameter|
Continuous if Sample Time = 0
|Scalar Expansion||Yes, of the parameters|
uses the Mean block to determine the mean value of a DC signal containing
a 12th harmonic ripple.
The model sample time is parameterized by the Ts variable set to a default value of 50e-6 s. Set Ts to 0 in the command window to simulate the model in continuous mode.
