About Me

Ph.D student at the department of Automatic Control since August 2015.

My field of research is event-based control and state estimation. I investigate optimization of event-trigger conditions for event-based estimation and control schemes in a stochastic setting. To sample and actuate optimally based on the current state of the process, rather than based on time, allows for a better performance and lower resource utilization than periodic schemes for the same average sampling rate.

You can find my personal page in Lund University's research portal here.

Systems where the state vector is intermittently reset play a fundamental role in the study of event-based control and estimation. Above is a classic 1D example of an integrator, where the state is reset to the origin whenever it hits the boundaries. The plot shows the propagation of the state's probability density over time. The density starts out Gaussian, but converges to a triangular distribution.
