The Computed sample time

Hi,

i get this error:

The computed sample Time 2E-09 is not an integer multiple of the fixed step size 1E-08. the period, pulse width and phase delay parameters of this block need to be integer multiples of the fixed step size.

can anyone help

Hi,

i try to simulate a DC/DC Converter in simulink with pulse width of 300 Khz, and i get this error

Hi,

i get this error:

The computed sample time (1.25E-06) is not an integer multiple of the fixed step size (1E-05). The period, pulse width and phase delay parameters of this block need to be integer multiples of the fixed step size.

Can anyone help me.Thanks in advance.

If the step size is 1 second, the sample time of any block could be 1, 2, 5, 10, etc. It can't be 2.3, 10.5 or smaller than 1 like 0.5, etc.

The easiest way for you is to change the step size to be 1.25E-6 if possible. You may have further issue though.

[Fangjun Jiang]

Based on your specification of Period (secs) and Pulse Width (% of period), Simulink calculated that the time incremental needs to be as small as 2E-09. But your fixed step size (1E-08) is larger. That is the error.

Double check your specification. Please note that if you want to specify 5% duty cycle, you should specify it as 5, not 0.05.

The computed sample time (0.0004) is not an integer multiple of the fixed step size (0.0084). The period, pulse width and phase delay parameters of this block need to be integer multiples of the fixed step size
