my Objectif is to get a frequency response of the open loop system of plant which will allow me to design the controller transfer function. after including the RMS filter, the Analysis tool of Simulink shows this error:
Simulink Control Design 1 Clear 02:22 PM Elapsed: 0.29 sec In "frestimate(modelname,op,io,in)",
the input signal "in" is a frest.Sinestream signal which has parameter values for "Frequency" and "SamplesPerPeriod" such that it inherently
has multiple sample times. Using such an input signal requires that samples rates belonging to the Simulink signals
where your linearization input and output points are located are either continuous
or fixed in minor time step and the linearization I/O io(2) does not satisfy this requirement.
Consider either changing the sample time of Simulink signal where io(2) is located to continuous sample time
or using frest.createFixedTsSinestream utility to create a sinestream signal that has a single sample rate.
Component:Simulink Control Design | Category:Frequency Response Estimation error
what I understood is that I have to use only one sample frequency which I cannot since i need the RMS filter. how can I get my frequeny response?
