Optimizing the performance of field crop sprayers by an H~infinity disturbance attenuation technique

摘要

In this paper, a new H~infinity -control technique is proposed, in order to attenuate nozzle disturbances which degrade the performance of field crop sprayers. The proposed technique relies on multirate-output controllers. Its main feature consists in reducing the original problem, to an associate discrete H~infinity -control problem for which a fictitious static state feedback controller is to be designed. The effectiveness of the method is demonstrated by several simulation results.
