New design conditions for PD discrete-time fault observers for linear system with disturbance is given. It enables to formulate design conditions using extended Lyapunov function as the set of linear matrix inequalities in the bounded real lemma structure. It is shown that such conditions provide better results considering the constrains implying from the fault time-difference norm. To encompass the...
The paper deals with the model-based compensation of friction in velocity and position controlled servomechanisms. A class of single degree of freedom mechanical systems with friction nonlinearity acting at the plant input is considered. Two approaches to friction compensation using dynamic model-based feedforward control and disturbance observer based feedback control are studied and compared to...
This paper discusses the automatic control of airplane in longitudinal and lateral-directional planes, during landing, using two neural network and dynamic inversion concept based adaptive control subsystems, having as components: linear observers, linear dynamic compensators, reference models, and Pseudo Control Hedging blocks in order to eliminate the adapting difficulties of the neural network...
The balancing of inverted pendulum along a vertical position by applying force to the cart is a typical problem in the area of automatic control. Its popularity derives from the fact that it is unstable without control. This article describes creation of the mathematical model, analyzing its behavior and state space controller design for subsequent use in programmable logic controller. Mathematical...
The paper addresses the developing method of an adaptive control structure for an anaerobic digestion process under the realistic assumption that some state variables are unmeasurable, the reaction kinetics are incompletely known and time-varying and moreover the influent pollutant concentration is completely unknown. More exactly, the process that is taken into account is a wastewater biological...
