Distributed System with Damping: Modal Tests and Digital Control.
Abstract
Experimental testing and control equipment has been purchased and set-up for the purpose of performing identification and control experiments on generic flexible structures. The ultimate goal of the test facility is to establish a laboratory capable of experimentally verifying control laws for distributed parameter systems. This is established by providing 1) a dynamic test facility coupled to a main frame computer system, 2) a microprocessor development system and 3) various flexible structures, actuators and sensors. During the one year period of the grant the hardware specified has been purchased and assembled. As the first step in using the equipment, several identification tests have been performed to measure the dynamic characteristics of a flexible structure. A composite beam was chosen as the test article with emphasis placed on measuring damping. In addition, as it is the intent of the laboratory to provide real data for the mathematics community. Data from a composite beam has already been sent electronically to researchers in identification theory at Brown University. The coupling of the computer aided test system and dynamic analyzer to a main frame computer system extends the use of the equipment to purely research algorithms rather than limiting the use to standard modal testing or modal analysis algorithms. Thus it is possible to use the laboratory to verify algorithms based on distributed parameter models rather than limiting the program to lumped mass models as other laboratories do.
