Abstract : The purpose of this thesis is to obtain the optimal open-loop control for plants that contain random parameters, using the expected value of a quadratic cost functional as the performance index. The basic assumption is that the plant parameters are time-invariant independent random variables with known probability density functions. Solutions to five examples are obtained using two methods: the first is an analytic method employing an extension of S.S.L. Chang's frequency domain techniques; the second is a computational method employing a gradient algorithm. Use is made of the Fredholm integral equation to determine whether solutions obtained are optimal. (Author)
