Using Sign Function and Absolute Function to Construct Nonlinear Function
Han Jing-qing · Control Engineering of China · 2008
The logical judgment is indispensable.Since some kinds of logical judgments can be realized by utilizing nonlinear functions,the intelligent control can be partially implemented by constrcuting proper nonlinear functions.A method that using the sign function and the absolute function to construct special nonlinear functions is proposed.Furthermore,the problem to approximate arbitrary first-class non-continuous functions by the special nonlinear functions is discussed.
