Another beam deflector control system design

Bernard Friedland

Research output: Contribution to conferencePaperpeer-review


A robust, non-adaptive compensator for control of a beam deflector is presented as an alternative to the adaptive design recently published by Gut-man, et. al. The compensator is designed by linear, quadratic state space methods using a third-order design model of the plant which includes an exogenous state to represent the reference input. This artifice leads to a compensator with "integral action", a feature which makes it possible to satisfy the performance requirements without the use of adaptive control. The design is evaluated by a simulation with a "truth model" that contains a representation of two parasitic resonances not accounted for in the design model. The design is found to have a dynamic response and a gain margin that meet or exceed the performance requirements.
