Abstract
The purpose of this paper is to present a new and efficient method for optimal design of placement and gains of actuators and sensors in output feedback control systems. The method extends the method developed by Levine and Athans by solving for optimal placement. The method also enhances the nonlinear programming approach developed by Schulz and Heimbold with the use of analytical expressions for the gradients of the performance function. The method is efficient and can handle a large number of optimization variables. Several numerical studies were performed for a two-dimensional structure. Multiple local minima for the performance function are possible for the optimal placement problem, and randomly generated initial values for the optimization variables were used to obtain a set of solutions. In all cases, even with 100 optimization variables, convergence was rapid.
