An asymptotically stable switched system visual controller for eye in hand robots

چکیده
Visual servoing methods are mmmonly classified as image based or position based, depending on whether image features or the robot pose is used in the feedback loop of the control law. Choosing one method over the other gives stability in the chosen state but surrenders all control over the other, which can lead to system failure if feature points are lost or the robot moves to the end of its reachable space. We present a hybrid switched system visual servo method that utilizes both image based and position based control laws. Through a switching scheme we present, this method wil l pmvide asymptotic stability in both the image and pose and prevent system failure.

متن کاملSoft Switching MBC Controller for MIMO Linear Hybrid Systems
Switching supervisory is the most important section of a feedback control process inMIMO hybrid systems. By choosing a non-compatible controller, system may go tounstable mode or high overshoot response. In this paper, a new method of switchingfor selecting MBC controllers is discussed. Results of the simulation show the MIMO(2-in 2-out) linear hybrid system can be switched stable and low overs...
متن کاملInteger-order Versus Fractional-order Adaptive Fuzzy Control of Electrically Driven Robots with Elastic Joints
Real-time robust adaptive fuzzy fractional-order control of electrically driven flexible-joint robots has been addressed in this paper. Two important practical situations have been considered: the fact that robot actuators have limited voltage, and the fact that current signals are contaminated with noise. Through of a novel voltage-based fractional order control for an integer-order dynamical ...

In this paper, H∞ controller is synthesized for networked systems subject to random transmission delays with known upper bound and different occurrence probabilities in the both of feedback (sensor to controller) and forward (controller to actuator) channels. A remote observer is employed to improve the performance of the system by computing non-delayed estimates of the sates. The closed-loop s...
متن کاملEnergy Based Limit Cycle Control of Rigid and Elastic Joint Robots
A new control law for elastic joint robots that allows to regulate an energy function of the system to a desired value is presented in this paper. Being able to either remove energy from the system or inject into it, oscillations can be both damped out and induced. The proposed nonlinear dynamic state feedback controller forces the system to evolve on a submanifold of the configuration space. T...
