A SYSTEMIC MODEL OF BIOFEEDBACK LEARNING

J. GALLEGO, L. LAURENTI‐LIONS

Mathematical models of biofeedback learning provide empirical laws of these processes and could be used in order to improve experiments. The systemic approach provides a…

BANG‐BANG CONTROL OF A SECOND‐ORDER NON‐LINEAR STABLE PLANT WITH THIRD‐ORDER NONLINEARITY

I. VAKILZADEH, A.A. KESHAVARZ

In this paper the design of a controller for a relay‐controlled second‐order non‐linear stable plant with third‐order nonlinearity is considered. The task of the controller is the…
