Resumen:
This paper focuses on the behaviour of variablestructure systems with dynamic control, particularly during thereaching mode of operation. It is shown that stability problemsmay arise during this reaching phase. The causes of these problemsare closely related with the problems of windup commonly found inconventional control systems with actuator constraints. Methods for stabilization of the reaching mode are proposed which arebased on the concepts of `realizable reference´ and observers.Well-known algorithms that have been previously proposed fromempiric ideas, can now be rigorously derived using these concepts.The theoretical framework developed by Kothare and co-workers inthe context of windup is generalized to study and design controlalgorithms for the reaching mode.
