This paper describes the use of angular position control approaches for a flexible robot manipulator with disturbance effect in the dynamic system. A nominal characteristic trajectory following (NCTF) controller is used to actively control the vibration of flexible structures. The controller design, which is comprised of a nominal characteristic trajectory (NCT) and PI compensator, is free from exact...
The control of car following is essential to its safety and its operational efficiency. For this purpose, this paper builds a linear, continuous and time-delay model of car following. And then, presents a controller based on an adaptive network fuzzy inference system (ANFIS) for the car-following collision avoidance system to adaptively control the speed of the vehicle. The relative distance and relative...
When designing the control loops for tokamaks, it is important to acknowledge the effects of time delays. An assumption sometimes made for tokamaks having superconducting coils is that these extra time delays will not have any undesirable effects on control. In fact, introducing extra delays into the axisymmetric control loops of certain superconducting tokamaks can have significant detrimental consequences...
There are analyzed the effects of the small delays in the feedback loop that inevitably lead the systems into an unstable situation. How small the delay must be in real conditions, such that to preserve the system stability, will be studied and analyzed for a robot manipulator. The case of an adaptive controller is also developed for the robot system actuated by brushed direct current motors in the...
