Mass distribution variations in helicopters cause significant adverse effects on helicopter flight. These variations are triggered by unwanted torques. These unwanted torques must be compensated for the sake of smooth and comfortable flight. This paper presents a robust control algorithm to overcome the fore-mentioned problem. The robust control algorithm is based on super twisting based 2-sliding...
This paper considers cross-coupling affects in a twin rotor system that leads to degraded performance during precise helicopter maneuvering. This cross-coupling can be suppressed implicitly either by declaring it as disturbance or explicitly by introducing decoupling techniques. The standard Hinfin controller synthesized by loop-shaping design procedure (LSDP) offers robustness at the cost of performance...
A new sliding surface has been proposed to handle cross-coupling affects in a twin rotor system. This cross-coupling leads to degraded performance during precise maneuvering and it can be suppressed implicitly either by declaring it as disturbance or explicitly by introducing decoupling techniques. Sliding mode control offers robustness against cross-coupling as well as performance along with the...
