Roy, ShibdasPetersen, Ian2022-09-20November 39781922107909http://hdl.handle.net/1885/272916We study robust H∞ coherent-classical estimation for a class of physically realizable linear quantum systems with parameter uncertainties. Such a robust coherent-classical estimator, with or without coherent feedback, can yield better disturbance-to-error performance than the corresponding robust purely-classical estimator for an uncertain plant. Moreover, coherent feedback allows for such a robust coherent-classical estimator to be more robust to uncertainty in comparison to the robust classical-only estimator.This work was supported by the Australian Research Council and the Singapore National Research Foundation.application/pdfen-AU© 2016 Engineers Australia201610.1109/AUCC.2016.78682202021-08-01
