  1. 16. A study on the application of machine learning algorithms in stochastic optimal control

    University essay from KTH/Matematisk statistik

    Author : Xin Huang; [2019]
    Keywords : ;

    Abstract : By observing a similarity between the goal of stochastic optimal control to minimize an expected cost functional and the aim of machine learning to minimize an expected loss function, a method of applying machine learning algorithm to approximate the optimal control function is established and implemented via neural approximation. Based on a discretization framework, a recursive formula for the gradient of the approximated cost functional on the parameters of neural network is derived. READ MORE

  3. 17. Stochastic Knock Control for Improved Efficiency

    University essay from Linköpings universitet/Fordonssystem

    Author : Jonas Vedin; Robert Widén; [2019]
    Keywords : Knock control; Stochastic knock control; Knock simulation;

    Abstract : Increasing the efficiency and performance of internal combustion engines is always of interest in the automotive industry. One limiting factor to achieve this in gasoline combustion engines is the ignition timing which can not always be set where optimal ignition efficiency and performance is obtained. READ MORE

  4. 18. Optimal driving decision based on energy and time costs

    University essay from KTH/Optimeringslära och systemteori

    Author : Sakina Huseynzade; [2019]
    Keywords : ;

    Abstract : Nowadays the industrial world has a common goal to build environment-friendly transportation and power-train systems. The first step for this aim is electrification of vehicles on the road which has remarkable influence on energy dependency and greenhouse gas emissions. READ MORE

  5. 19. A Model-Predictive-Control Based Smart-Grid Aggregator

    University essay from KTH/Optimeringslära och systemteori

    Author : Amanda Paulus; [2018]
    Keywords : ;

    Abstract : Intermittent energy source usage, such as solar and wind power, is continuously increasing. Intermittent energy sources are highly dependent on prevailing weather conditions, resulting in stochastic electricity generation. The expected stochasticity in electricity generation will cause issues for the current power grid. READ MORE

  6. 20. Optimal Control of a Stochastic Heat Equation with Control and Noise on the Boundary

    University essay from Linnéuniversitetet/Institutionen för matematik (MA)

    Author : Thavamani Govindaraj; [2018]
    Keywords : Linear Quadratic Control; Stochastic Heat Equation;

    Abstract : In this thesis, we give a mathematical background of solving a linear quadratic control problem for the heat equation, which involves noise on the boundary, in a concise way. We use the semigroup approach for the solvability of the problem. To obtain optimal controls, we use optimization techniques for convex functionals. READ MORE
