This paper proposes a global cooperative control framework to address leader-follower consensus of constraints subsystems of industrial plants, in which each subsystem is modeled as an agent and all the subsystems and networks of information flow construct a multiagent system. The focus of this paper is to solve the global leader-follower consensus for multiagent systems with input saturation via...
This paper investigates the leader-follower problem in the presence of potential actuator faults. We focus on continuous-time multi-agent uncertain systems with a directed network topology. Time-varying fault parameters are considered, which relax the assumption in the prior work that the fault parameters of all followers must be fixed. We assume that these parameters can be sampled in an intermittent...
This paper deals with the problem of fault-tolerant control (FTC) for flexible spacecraft with partial loss of actuator effectiveness and time-varying input delay. An adaptive fault-tolerant controller is designed by using the online estimation, in which an addition control term is added into the normal control law. This compensation method can reduce the fault effect and don't need the isolation...
In this paper, we design a fuzzy fault-tolerant tracking controller for the Mars Entry Vehicle (MEV) with the partial failure of actuator, external disturbance and input delays. Firstly, we divide the attitude system of MEV into slow subsystem and fast subsystem. By using the slow subsystem, we can get angular velocity and then choose this angular velocity as the reference angular velocity for the...
This paper presents the development and validation of an automatic steering controller that has been successfully implemented on a 18.3-m articulated bus for revenue service in Eugene, Oregon, USA. The automated steering system provides both lane keeping and S-curve precision docking on a 4-km-long narrow and curving urban segment with six stations and mixed traffic lanes while the operator controls...
SaaS is a new delivery model for the software development and application. Providers tend to make their SaaS products achieve higher level of maturity, serves more people, satisfy more different individual requirements, while maintaining efficiency and flexibility. This paper introduces a new SaaS application model called SaaS with tenancy agency. It adds two new layers: tenancy process layer and...
In this paper, a multirate cyclic pseudo-downsampled iterative learning control (ILC) scheme is proposed. The scheme has the ability to produce good learning transient for trajectories with high frequency components and/or initial state errors. The proposed scheme downsamples the feedback error and input signals every m samples to arrive at slow rate signals. Then, the downsampled slow rate signals...
