Networked control system (NCS) is a kind of closed loop control systems where the sensors, the controller and the actuators exchange data through network. Because the networks, in which the band width is limited, are introduced in the systems, some new issues appear unavoidably. At present, the research of networked control system becomes a focus area in control engineering. According to the characteristics...
Chaos synchronization system is significant in future practice. Impulsive control is an effective method for generation of chaos synchronization. Based on analysis of critical state in chaos systems, a new impulsive synchronization approach is put forward, and the construction of synchronic system is schemed. Through analyzing the critical state of the strange attractor in chaos systems, it reveals...
This paper presents the problem of trajectory tracking control for the nonholonomic six-wheeled mobile robot. Based on backstepping control algorithm, a switch function for quasi-sliding mode control is designed and a quasi-sliding mode controller with global asymptotically stability is proposed for the kinematic model. This method simplifies the controller design and is applicable to the trajectory...
The design of global sliding mode control (GSMC) based on reaching law is studied and applied to the controller design of buck converter in this paper. The simulation results verify the validation of the global sliding mode controller with reaching law.
In this paper a model and a nonlinear control scheme for an atomic force microscope are developed. For this reason a backstepping control algorithm is developed to achieve asymptotic cantilever tip tracking for bounded tip trajectories. In addition, the micro cantilever is modeled by the interaction between sample and cantilever with the Van der waals attraction/repulsion force (i.e., the interaction...
Atomic force microscope (AFM) can be used as nano-robotics manipulation tool for nanoparticle positioning, pushing, indenting, cutting and etc. control the vibration behavior of AFM and make the microcantilever tip track specified trajectory is very crucial to appropriately manipulate particles in nanoscales. The novel combined sliding mode approach has been investigated in this paper to obtain robust...
