Coefficient bounds for functions with a positive real part are used in a rather novel way to find sharp bounds for the first six coefficients of a function which is inverse to a regular normalized ...

There is no definitive rule for choosing T_f, however, it's recommended to start with a small value such as 0.01 or 0.1 times the derivative time constant T_d = K_d/K_p.

To obtain the inverses of time-varying matrices in real time, a special kind of recurrent neural networks has recently been proposed by Zhang et al. It is proved that such a Zhang neural network (ZNN) ...
