DYNAMIC MODELING AND CONTROL SYSTEM FOR A SHROUDED PROPELLER SYSTEM

摘要

This paper is presents the dynamic modelingrnand control system design of a shroudedrnpropeller based on the classical method. Therndynamic model has been designed usingrnnonlinear aerodynamic models by VLM (VortexrnLattex Method). The aerodynamic analysis ofrnthe model is indispensible for the improvementrnof its accuracy and for designing the controller.rnBased on the LTI model of hover, classicalrnSISO control has been used for the stabilizationrnof the vehicle. The controller for hover has beenrndesigned using the linear SISO control approach.rnFurther, the control system design has beenrnbased on the precise dynamic model for morernaccurate controller gain selection. The proposedrncontrollers have been presented along with thernsimulation results. In conclusion, thernperformance of the proposed approach has firstrnbeen validated by numerical simulation and thenrnby a series of flight tests.
