High control bandwidth is usually restricted in a photoelectric tracking system (PTS) based on Charge-Couple Device(CCD) with time delay, which hinders good performance. Generally, model-based delay-compensation controller called Smith predictor (SP) can help increase the gain to promote by separating delay from loop. However, performance promotion insufficient because still stays forward chann...

Goal-directed behavior is a hallmark of cognition. An important prerequisite to goal-directed behavior is that of prediction. In order to establish a goal and devise a plan, one needs to see into the future and predict possible future events. Our earlier work has suggested that compensation mechanisms for neuronal transmission delay may have led to a preliminary form of prediction. In that work...

Time delay plays a critical role in the performance of real-time Networked Control Systems (NCS). It can destabilise the NCS as it deteriorates the performance and stability of networked control systems. Communication networks inevitably introduce delays in NCS. Therefore, it is necessary to compensate the time delay. The time taken by the system depends upon the characteristics of the network ...

This paper studies congestion control in local wireless networks supporting transmission control protocol (TCP) under random early detection (RED). In general, congestion delays may cause instability of the routers running active queue management (AQM) protocols such as RED. Moreover, its management efficiency could be reduced by serious queue oscillation. To improve these two drawbacks, we pro...

In this paper a time delay compensation control structure for a robot teleoperation system is presented. The structure design was made considering 1.9-seconds time delay in the communication between the remote and local stations. The objective is to control both the remote manipulator’s position and force. Force and position signals are fedback to the local station so that the human operator fe...

Control systems with digital communication between sensors, controllers and actuators are called as Networked Control Systems (NCSs). In general, NCSs encounter with some problems such as packet dropouts and network induced delays. When plant uncertainty is added to the aforementioned problems, the design of the robust controller that is able to guarantee the stability, becomes more complex. In...
