Hallo dear Jamali / Ryan G,
First of all, sorry for my english, i hope you can read it and understand me well !
i have the same problem using fuzzy logic ! After giving all the rules and implement a fuzzy block in simulink, i have a permanent zero as output !
while looking in the fuzzy rules viewer, it seems all to be ok... but while implement it in Simulink..."don´t get enough zero" !!!
I look in the FIS WIZARD (Model Browser) and i have see that they are some ports who are not connected ( maybe the reason of this permanent zero )... i have made some screenshots and maybe i can mail them to you !
I suspect that this error is running under Matlab 2010a , while when i use Matlab 2012 i don´t have this problem ( but i have to test it one more time
I hope you can understand my sentences and maybe you have a solution of this bug
