چکیده

The design process and complexity of existing safety controls are heavily determined by the geometrical properties environment, which affects proof convergence, scalability, performance robustness, numerical efficiency control. Hence, this brief proposes a variable structure control to isolate environment’s from structure. A super-twisting algorithm (STA) is used achieve accurate trajectory tracking robust Safety designed solely based on distance measurement. First, nominal model for obstacle avoidance derived, where realistic system constraints considered. well-suited border patrol with analytically proven stability results. uses measurement maintain safe compensating robot’s angular velocity. Also, supervisory logic constructed unify features, operational precision under parametric uncertainty. proposed modular minimal tuning parameters, reduces computational burden improves scalability. effectiveness method verified against various case studies.

Variable Structure Control of Pendulum-driven Spherical Mobile Robots

In this paper, we propose a hierarchical sliding mode control approach for a fixed point regulation of pendulum-driven spherical mobile robots. A simplified dynamic model is established for their longitudinal motion and the controller is designed to have double layer structure because the system is divided into two subsystems. In the first layer, the sliding surfaces are hierarchically designed...

Augmented Invariance Control for Impedance-controlled Robots with Safety Margins

Various robotic applications require enforcing constraints, to achieve task performance or to hinder the robot from causing danger. Especially in human-robot-interaction, collision avoidance and velocity limits are crucial for safety. A promising approach to enforce adherence to safety margins is invariance control. Considering the system dynamics, it corrects a nominal control based on a switc...

Impedance Control of Robots Using Voltage Control Strategy Revisited

In this note, we show that the impedance control strategy proposed in the paper is not feasible from practical implementation point of view. Next, a robust impedance controller is proposed for electrically driven robots using Fourier series (FS). The fact that robots' actuators have limited voltage is also considered in controller design procedure. In comparison with other impedance controllers...
