“…In spite of showing theoretical results of the ETC advantages [52]- [59], few works report experimental results (laboratory testing with real systems) in the framework of robotic manipulators. For instance, ETC has been applied to the stabilization of the underactuated inverted pendulum [60], UAVs [61] and the (3, 0) mobile robot [62].…”

Periodic Event-Triggered Control for the Stabilization of Robotic Manipulators

This paper proposes a periodic event-triggered control (PETC) design applied to nonlinear robotic systems for joint space stabilization. The update of the control signal is based on a predefined triggering mechanism that periodically considers state measurements. So, continuous state measurements required in the continuous event-triggered control (CETC), are no longer needed in this proposal. The main advantages of the proposal are: 1) to assure the convergence of the closed-loop trajectories to a compact ball centered in the origin of the error space, and 2) the relaxation of continuous measurements for the evaluation of the event condition which implies a more suitable design for real-time implementation purposes. Experimental comparative results of the proposed design with a time-triggered control (TTC) scheme show that the PETC can present suitable performance with a significant reduction of 82.20% of the controller updates mainly given in the steady-state of the closed-loop system. This implies a decrement of the computation resources due to information transfer.

“…In [35], the radial-basis-function-based neural network was employed in the event-triggered attitude tracking control of the spacecraft, such that the robustness of the closed-loop system was enhanced towards parameter uncertainties and external disturbances. Event-triggered control method was also successfully utilized into attitude synchronization of the spacecraft [36], [37]. However, the integrated translational and rotational tracking control of the spacecraft to achieve fly-around missions is not considered in [32]- [37].…”

“…Moreover, note that the above integrated translational and rotational control methods in [17], [19]- [23] and the attitude control methods [32]- [37] either only guarantee convergence of the tracking error, or only enable the tracking error to fall into a bounded residual set, and cannot ensure the transient and steady control performance of the closed-loop system such as overshoot, convergence speed, and maximum steadystate error. To achieve the desired transient and steady control performance, the prescribed performance control (PPC) is proposed in [38]- [41].…”

“…In contrast with the control schemes in [46]- [51] which need to real-time update of the control input, an eventtriggered control scheme is designed to reduce the controller updated times and the Zeno behavior is excluded. Different from the event-triggered attitude control schemes [32]- [37], the designed event-triggered scheme is combined with PPC such that the closed-loop system has the prescribed transient and steady performance of full states.…”

This paper investigates the event-triggered integrated attitude and position robust control problem for non-cooperative fly-around mission with prescribed performance in the presence of uncertain dynamics and external disturbances. For the requirement of line-of-sight orientation, a coupled motion model of relative position and attitude of the spacecraft is established, where the relative orbit model is described in the line-of-slight frame. Based upon the prescribed performance functions and the model error transformation, an integrated robust adaptive controller is proposed such that the desired fly-around trajectory and attitude orientation can be tracked simultaneously. Moreover, an event-triggered condition is also designed, such that the number of control input updates can be reduced. By means of the constructed event-triggered condition, the closed-loop system still possesses the predetermined control performance, and Zeno phenomenon can be avoided. Simulation results are presented to verify the effectiveness of the proposed controller. INDEX TERMS event-triggered, prescribed performance , non-cooperative spacecraft, fly-around mission, integrated attitude and position.

Summary This article investigates the fault‐tolerant attitude synchronization control problem for a team of formation flying satellites. The dynamics of each satellite is influenced by nonlinearities, parametric perturbations, external disturbances, and actuator faults. A robust fault‐tolerant formation flying controller is proposed, via the linear quadratic regulation method and the robust compensating theory, for the satellite team to achieve the desired attitude synchronization. Robustness analysis shows that the attitude tracking error of the global closed‐loop control system can converge into a given neighborhood of the origin in a finite time. Numerical simulation results validate the effectiveness and advantages of the proposed formation flying controller for the satellite team.
