Abstract

The effect of time delay on the control of a single and two coupled torsion bar structures is explored using analytical expressions solved numerically and numerical simulations of the response of the systems. The maximum gain for stability is determined over a range of time delays for collocated and non-collocated derivative control numerically based on a model of the systems. We found that when larger time delays were used, non-collocated derivative control remained stable for a wider range of gain values than collocated control did. The design of a control system using non-collocated derivative control and implementing a single actuator is also explored.
