Description
This paper considers the application of LQG integral control theory to a problem of cavity locking in quantum optics. The cavity locking problem involves controlling the error between the laser frequency and the cavity frequency. A model for the cavity system, which comprises of a piezo-electric actuator and an optical cavity is determined in the frequency domain using a subspace identification method. An LQG controller which includes integral action is synthesized to stabilize the frequency of...[Show more]
