Abstract: In this article, we investigate the stability analysis of a polynomial-fuzzy-model-based control system by employing a new form of approximate membership functions called Chebyshev ...

Polynomials and power functions are the foundation for modelling non-linear relationships. Polynomial functions such as quadratic, cubic and quartic model variables raised to exponents of different ...

This paper uses a degree 3 polynomial approximation for sigmoid (useful in the interval [-5, 5]). It also has a degree 1 approximation with more loss, but it's there. This would be useful to use for ...
