WebbThe function is (0.4/ (2700 s+1))exp (-4200s). Iv tried the Transfer Fcn block, but it doesn't work with the exp (-4200 s) part.. The Transfer Fcn block only works with a quotient of two polynomials. If you split up the TF into the polynomial and exponential parts, you can combine them later with a product block. Webbsyms tF = exp( t ^2) ;subs (F,0) ans =1 Works fine for me. My guess is you defined a variable called exp. Or maybe something silly like like subs. Try typing whos at the command line, and look to see if you defined a variable with a name that is allocated normally to some function you then tried to use. The simple answer is ... DON'T DO THAT!

Such a system can't be represented with transfer functions. In Simulink, one way (though not the only way) is to implement the system using integrators and logic to control the value of the model parameters. fitindex resistance trainer kit

Webb10 okt. 2024 · It is not possible to specify an exponential delay in the transfer function other than the form exp (-M*s) when using the laplace variable. However, this delay could be specified by seperating the terms as exp (- (z/v)*s))*exp (m/ (s + k2))*exp (- (k1*z/v)) where the last two terms are constant gains for the transfer function. Webb18 juli 2024 · Answers (1) Aquatris on 18 Jul 2024 Exponential term is simply a time delay so you can treat your transfer function as; H (s) = 1/s - exp (-0.01s)* (1/s) The 1/s transfer functions can be implemented using transfer function block and the exp (-0.01s) can be implemented using transport delay block.

"Webb26 aug. 2024 · So, the Zero-Pole block is where you define the part of the transfer function without the exponential, and the Delay block will serve as the exponential part. And of course, to improve the presentation of the blocks, maybe making it as a subsystem (maybe even plus an appropriate mask) would make it even nicer.
