Designing Pitch Angle Compensator for an UAV and Robustification it with Bee Colony Optimization Algorithm

Mohammad Hosein Alizadeh; Alireza Toloei

Volume 8, Issue 1 , April 2024, , Pages 1-14


  The intended aircraft in this issue is an UAV type, capable of performing multiple missions. In this paper, after the linearization of the pitch channel, the transfer function for important points is extracted. After that, a robust classic compensator and an angular velocity damper are designed. According ...  Read More
