Electro-hydraulic actuators (EHA) have recently played a significant role in modern industrial applications, especially systems requiring extremely high precision. This can be explained by EHA’s ability to precisely control the position and force through advanced sensors innovative algorithms. One of promising approaches improve accuracy for EHA is applying classical algorithms, which proportio...

This paper presents a novel approach for designing reconfiguration blocks fault hiding of linear systems subject to actuator faults based on the passivity/dissipativity theory. For this purpose, concept passivation block is used design virtual actuators (VAs) which guarantee that faulty plant achieves desired passivity indices and consequently stability. Linear matrix inequalities (LMI)-based c...

This paper presents a method for predicting the power consumption of piezoelectric actuators utilized for active vibration control. Analytical developments and experimental tests show that the maximum power required to control a structure using surface-bonded piezoelectric actuators is independent of the dynamics between the piezoelectric actuator and the host structure. The results demonstrate...

In this paper control forces and torques automatic distribution algorithms for a vehicle actuators are considered. Base control algorithm is designed by position and path control method for vehicles [1] – [3]. This control algorithm is based on kinematics and dynamics equations of vehicle. Distribution of control forces and torques between actuators is solved by applying of the pseudoinverse ma...

in this paper, we try to use modeling based on singular perturbation theory, in order to control satellite attitude during the wide rolling angle maneuvering through nonlinear h∞ control strategy. differential equations describing dynamics of the satellite are presented first, and by choosing the appropriate dynamic model for actuators and based on the standard singular perturbation model, the ...
