I try to tune a PID-Controller in Matlab2010b if i use a discrete one i get the error Message "The second input argument of the "d2d" command must be a positive scalar." if i use a continuous one i get "Input to SVD must not contain NaN or Inf." what i have to pay attention that this block works fine? My system can became NaN due to a Sqrt-expression….
