| dc.description.abstract | This paper presents the results of an experimental procedure carried out to determine the response time of a sponge type magnetorheological (MR) damper to electrical inputs. The promptness of an actuator is a fundamental requirement for real-time structural control applications, especially when bang-bang controllers are used to generate the control signal. This type of controllers are frequently used to change the operating current in the electromagnet of MR dampers in order to create a bi-state control mode by switching on and off the device between high and low damping states, respectively. Thus, bi-state control signals can be modelled as step inputs or square waveforms that must be reproduced as fast as possible by the driving electronics and the MR actuator. In this work a simplified methodology for response time estimation of a small sponge type MR damper to step current inputs with and without mechanical excitation is presented. The results obtained with the experimental tests are analyzed and discussed. | pt_PT |
