This paper proposes some principles for fault management of longitudinal control of automated vehicles in AHS. Systems faults may be broadly divided into software and hardware. Software fault management is briefly addressed. These faults can be avoided by proper controller design, rigorous algorithm development, correct and robust code construction, simulation and real-time run test. Emphases are put on hardware faults. Hardware faults which may appear in practice are classified according to their likelihood of appearance, impact on safety, robust stability within controller bandwidth and maneuverability. The most prominent cases are those when communication and/or radar are in fault. From control viewpoint, they have very strong impact on string stability. The main difficulties in these cases are: (a) Some or all of the three parameters: relative distance, speed and acceleration, are not directly available; (b) Measurements of these parameters contains some noise; (c) Filtering and estimation of these parameters lead to some time delay and discrepancy. General principle of control strategy for each fault case is proposed. Corresponding string stability of the platoon is briefly analyzed. Consideration in this paper is in higher level. To practically implement each of these strategies will be addressed in future works.

This paper is concerned with the optimal distributed impulsive controller design for globally exponential synchronization of nonlinear dynamical networks with coupling delay. By the Lyapunov-Razumikhin method, a novel criterion is proposed to guarantee the global exponential synchronization of the coupled delayed network with distributed impulsive control in terms of matrix inequalities. The sum of coupling strengths of the distributed impulsive control is minimized to save the control effort. Finally, the effectiveness of the proposed method has been demonstrated by some simulations.

Purpose This paper aims to investigate the distributed formation control problem for a multi-quadrotor unmanned aerial vehicle system without linear velocity feedbacks. Design/methodology/approach A nonlinear controller is proposed based on the orthogonal group SE(3) to obviate singularities and ambiguities of the traditional parameterized attitude representations. A cascade structure is applied in the distributed controller design. The inner loop is responsible for attitude control, and the outer loop is responsible for translational dynamics. To ensure a linear-velocity-free characteristic, some auxiliary variables are introduced to construct virtual signals in distributed controller design. The stability analysis of the proposed distributed control method by the Lyapunov function is provided as well. Findings A group of four quadrotors with constant reference linear velocity and a group of six quadrotors with varying reference linear velocity are adopted to verify the effectiveness of the proposed strategy. Originality/value This is a new innovation for multi-robot formation control method to improve assembly automation.

A distributed supervisory controller is proposed to achieve battery component swapping modularity (CSM) for a plug-in hybrid electric vehicle (PHEV). The CSM permits the designer to distribute a part of the supervisory controller to the battery module such that the PHEV can use a range of batteries while providing corresponding optimal fuel economy. A novel feedback-based controller for the charge sustaining mode is proposed to facilitate distributed controller design for battery CSM. The method based on sensitivity analysis of the control signals with respect to the battery hardware parameter is introduced to define the controller distribution architecture. The distributed controller gains are obtained by solving a bilevel optimization problem using the collaborative optimization and the augmented Lagrangian decomposition methods. The simulation results demonstrate that the proposed distributed controller can achieve battery CSM without compromising fuel economy compared to the centralized control case.
