2. 1. Methods for Stochastic Optimal Control under State Constraints

   Author : Per Rutquist; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; control theory; optimal control; stochastic systems; Hamilton-Jacobi-Bellmanequation; Fokker-Planck-Kolmogorov equation;

   Abstract : This thesis looks at a few different approaches to solving stochas-tic optimal control problems with state constraints. The motivatingproblem is optimal control of an energy buffer in a hybrid vehicle,although applications are abundant in a number of areas. READ MORE

4. 2. On Infinite-Horizon State-Constrained Optimal Control - With Application to a Fuel Cell APU

   Author : Per Rutquist; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : This thesis presents a method for computation of optimal control policies for state-constrained, time continuous, infinite-horizon systems. It is applicable to input-affine systems where the stochastic contribution can be modeled as a vector of white noise signals that is added to the control input, with the intensity of the noise being inversely proportional to the control cost.
