On exponential utility and conditional value-at-risk as risk-averse performance criteria

KM Smith, MP Chapman - IEEE Transactions on Control …, 2023 - ieeexplore.ieee.org
The standard approach to risk-averse control is to use the exponential utility (EU) functional,
which has been studied for several decades. Like other risk-averse utility functionals, EU …

CVaR-based safety analysis in the infinite time horizon setting

C Wei, M Fauß, MP Chapman - 2022 American Control …, 2022 - ieeexplore.ieee.org
We develop a risk-averse safety analysis method for stochastic systems on discrete infinite
