Chance Constrained Stochastic Optimal Control for Linear Systems with a Time Varying Random Control Matrix
This work proposes an open-loop methodology to solve chance constrained
stochastic optimal control problems for linear systems with a stochastic
control matrix. We consider a joint chance constraint for polytopic
time-varying target sets under moment and unimodality assumptions. We
reformulate the chance constraint into individual biconvex constraints using
the one-sided Vysochanskij-Petunin inequality. We demonstrate our methodology
on two spacecraft rendezvous problems. We compare the proposed method with the
scenario approach and moment-based methods based on Cantelli's inequality.Comment: Final Submission to CCTA 202
Chance Constrained Stochastic Optimal Control for Linear Systems with Time Varying Random Plant Parameters
We propose an open loop control scheme for linear systems with time-varying
random elements in the plant's state matrix. This paper focuses on joint chance
constraints for potentially time-varying target sets. Under assumption of
finite and known expectation and variance, we use the one-sided
Vysochanskij-Petunin inequality to reformulate joint chance constraints into a
tractable form. We demonstrate our methodology on a two-bus power system with
stochastic load and wind power generation. We compare our method with situation
approach. We show that the proposed method had superior solve times and
favorable optimally considerations.Comment: Final submission for ACC 202
