Abstract : The purpose of this thesis is to obtain the optimal openloop 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 timeinvariant 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)
