Optimal Direction-Dependent Path Planning for Autonomous Vehicles
Shum, Alex (University of Waterloo, 2014-04-24)The focus of this thesis is optimal path planning. The path planning problem is posed as an optimal control problem, for which the viscosity solution to the static Hamilton-Jacobi-Bellman (HJB) equation is used to determine ... -
PID Control of Systems with Hysteresis
Shum, Alex (University of Waterloo, 2009-04-29)Hysteresis is exhibited by many physical systems. Smart materials such as piezoelectrics, magnetostrictives and shape memory alloys possess useful properties, especially in the field of micropositioning, but the control ...
