Plenary lecture „Variable structure control with sliding modes - from basic concepts to current research trends” will be given by professor Andrzej Bartoszewicz
The main purpose of control engineering is to steer the regulated plant in such a way that it operates in a required manner. The desirable performance of the plant should be obtained despite the unpredictable influence of the environment on all parts of the control system, including the plant itself, and no matter if the system designer knows precisely all the parameters of the plant. Even though the parameters may change with time, load and external circumstances, still the system should preserve its nominal properties and ensure the required behavior of the plant. In other words, the principal objective of control engineering is to design systems which are robust with respect to external disturbances and modelling uncertainty. This objective may be very well achieved using the sliding mode technique which is the main subject of this talk.
The theory of variable structure systems (VSS) with sliding modes is currently one of the most significant research topics within the control engineering domain. Therefore, this paper presents a brief tutorial introduction to the theory of sliding mode control (SMC), and then points out the most important research trends in this field. Both continuous and discrete time sliding mode controllers for single- and multi-input systems are considered. Important new results on the reaching law based controller design, chattering elimination, optimal sliding surface selection and reaching phase minimization are discussed.
