How to define the transfer function with exp
조회 수: 24(최근 30일)
I cannot make this transfer function either in matlab or in simulink, It has a wierd delay! can anyone help me please?! exp means a delay?! T(z,s) is output temperature and Tin(s) is input temperature.
s: is the laplace variable z,v,k1,k2,m(z) are constant
if gives this error ??? Error using ==> tf.exp at 31 The input argument of the "lti/exp" command must be a transfer function of the form -M*s.

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.
