Bias in the Estimate of a Mean Reversion Parameter for a Fractional Ornstein-Uhlenbeck Process
Ng, Wai Man (University of Waterloo, 2017-01-19)In this thesis we studied the estimation bias of the least squares estimate of the mean reversion parameter, when the underlying dynamics is governed by fractional Brownian motions. Fractional Brownian motion is a ... -
Energy Shaping for Systems with Two Degrees of Underactuation
Ng, Wai Man (University of Waterloo, 2012-01-11)In this thesis we are going to study the energy shaping problem on controlled Lagrangian systems with degree of underactuation less than or equal to two. Energy shaping is a method of stabilization by designing a suitable ...
