Passivity Based Control of the Compass Gait Biped
نویسنده
چکیده
In this paper we discuss the passivity based control of the two-link robot known as the Compass Gait Biped. Starting from a narrow region of initial conditions, the compass gait biped is capable of locomotion down shallow inclines without actuation or feedback control of any kind. We will discuss some feedback control strategies that can exploit these passive dynamics by shaping the energy of the system. Using potential energy shaping we can make the passive limit cycle slope invariant. We also discuss the use of switching control to address the sensitivity to initial conditions and robustness to disturbances.

Optimal Gaits For Compass-Like Biped Robot
With free walk velocity; the individual will naturally enlist the speed that will provide maximum energy efficiency. Inspired by this idea, we exploit a passivity based control strategy to study, the preferred walking gait of a compass-like biped robot. In fact, for any ground slope, we use a dynamic optimization of the mechanical cost which is proportional to the mechanical work in the system ...
متن کاملFurther results on control of the compass gait biped
This paper continues our investigations into the passivity-based control of the compass gait biped. It was shown in [14] for the compass gait biped, and in [15] for the general case, that a passive limit cycle for a given constant slope can be made slope invariant via potential energy shaping control. In this paper we consider the application of total energy shaping to this problem. Using a con...
متن کاملLimit Cycles in a Passive Compass Gait Biped and Passivity-Mimicking Control Laws
It is well-known that a suitably designed unpowered mechanical biped robot can \walk" down an inclined plane with a steady periodic gait. The energy required to maintain the motion comes from the conversion of the biped's grav-itational potential energy as it descends. Investigation of such passive natural motions may potentially lead us to strategies useful for controlling active walking machi...

This paper employs nonlinear disturbance observer (NDO) for robust trajectory-free Nonlinear Model Predictive Control (NMPC) of biped robots. The NDO is used to reject the additive disturbances caused by parameter uncertainties, unmodeled dynamics, joints friction, and external slow-varying forces acting on the biped robots. In contrary to the slow-varying disturbances, handling sudden pushing ...
متن کاملFrom Passive Dynamic Walking to Passive Turning of Biped walker
Dynamically stable biped robots mimicking human locomotion have received significant attention over the last few decades. Formerly, the existence of stable periodic gaits for straight walking of passive biped walkers was well known and investigated as the notion of passive dynamic walking. This study is aimed to elaborate this notion in the case of three dimensional (3D) walking and extend it f...
