syserr.m

模糊神经网络采用matlab编程 o install NEFCON follow these steps: 1. Unpack the tar file NEFCON.TAR into your MA

function ferr = syserr(input, bound) 
%SYSERR Default external error function (using bounds) for NEFCON
% The return value must be in [-1,1].
% Parameters:
%  simulink system dependend:
%   input(1) dx     (P) 
%   input(2) dx'    (D) 
%   input(3) F(dx)  (I) 
%  generator dependend (only set if nefcon bounded signalgenerator is used)
%   bound(1) signal 
%   bound(2) upper bound 
%   bound(3) lower bound 
%   bound(4) system output 
%   bound(5) system output derivative
