Citações
"Optimization solvers used in optimal controllers usually require powerful computers that can usually increase the payload of the robot which is not desired considering the conflicting requirements of legged-aerial robots."
"The momentum observer is also preferred because of the ability to avoid the inversion of the mass inertia tensor and eliminating the need of an estimating the joint accelerations."
