This paper presents a delay compensator fuzzy control for trajectory tracking of omni-directional mobile robots. Fuzzy logic control (FLC) of the robots is a suitable strategy for dealing with model uncertainties, nonlinearities and disturbances.  On the other hand, in many robotic applications such as mobile robots, delay phenomenon is able to substantially deteriorate the behavior of system's...

Considering the problems of model uncertainties, higher harmonics, uncertain boundary conditions, external excitations, and system time delay in practical vibration control system, a novel active method is proposed to suppress thin plate structure with acceleration sensor piezoelectric bimorph actuator this paper. First, nonlinear extended state observer (NESO)-based controller designed ensure ...

—In this paper, we propose and prove the scheme by stabilizing the fiber link time delay in the increase of the signal’s (RF) transmitted phase stability. Let radio frequency signals (RF) transmit between the intermediate node and a distal end to obtain the difference of time delay. The faster and smaller proportion of delay fluctuation are eliminated by the piezoelectric fiber stretchers (PZT...

With the integration of communication networks and distributed control in modern manufacturing and process industries, networked control systems (NCSs) are becoming increasingly important due to its simplicity, scalability, flexibility, and cost effectiveness. However, there are still significant technical barriers that limit the applications of NCS technologies. Two challenges are network-indu...

Abstract: The dead-time effect, as an intrinsic problem of the converters based on the half-bridge unit, leads to distortions in the converter output. Although several dead-time effect compensation or elimination methods have been proposed, they cannot fully remove the dead-time effect of blanking delay error, because the output current polarity is difficult detect accurately. This paper utiliz...
