In software-defined networks (SDNs), controller placement is a critical factor in the design and planning for future Internet of Things (IoT), telecommunication, satellite communication systems. Existing research has concentrated largely on factors such as reliability, latency, capacity, propagation delay, energy consumption. However, SDNs are vulnerable to distributed denial service (DDoS) att...

In this paper, we consider the stabilization controller for some desired trajectory of nonlinear systems. For such a problem, it should be one of the best strategies to apply the linear time-varying controller for linear approximate model around the trajectory. However, because a controller design procedure for linear time-varying system is not necessarily simple, some other methods like variou...

In this paper an analysis is made of the influence of the sampling period in the control performance of a pole-placement adaptive controller for a real-time distributed control system under output jitter conditions. Results show that the lower the sampling frequency the better control performance is obtained for the same jitter conditions. Key-Words: jitter, real-time systems, distributed contr...

A new parametrization for a linear system is presented. This parametrization is the basis for two approaches to design an adaptive controller for pole placement. One approach is based on parameter estimation and requires sufficient excitation, while the other, the model reference adaptive pole placement, uses a reference model and an augmented error. It is shown that the two distinct approaches...

Interaction using depth-sensing cameras has many applications in computer vision and spatial manipulation tasks. We present a user study that compares a short-range depth-sensing camera-based controller with an inversekinematics keyboard controller and a forward-kinematics joystick controller for two placement tasks. The study investigated ease of use, user performance and user preferences. Tas...

This paper proposed control strategies for the modern mechatronic Continuously Variable Transmission (CVT) System using three different techniques; The Ziegler-Nichols, Linear Quadratic and Pole-Placement methods. The results of the system responses of the designed control schemes were successfully simulated using MATLAB. Comparing the results showed that controller implemented using the Pole-P...

The predictive pole-placement control method introduced in this paper embeds the classical pole-placement state feedback design into a quadratic optimisation based model-predictive formulation. This provides an alternative to model-predictive controllers which are based on linear-quadratic control. The theoretical properties of the controller in a linear continuous-time setting are presented an...
