Optimal actuator placement with minimum worst case distortion criterion

摘要

This paper deals with optimal actuator placement in truss structures for quasi-static shape control using the worst case distortion criterion. This criterion is the worst case value of a performance measure obtained through a constrained min-max procedure which leads to an eigenvalue problem. Optimal actuator placement in large truss structures is a formidable task. In this paper we use and compare the performances of Simulated Annealing (SA), Exhaustive Single-Point Substitution (ESPS) and Single Location Iterative Minimization (SLIM), a sequential minimization technique presented herein, in solving this design problem.
