This paper presents a new PID and PID-like controller tuning method for single-inputsingle-output linear time invariant system. Th tuning method permits the designer to specify a set of desired stable regions, joint or disjoint, in the complex root plane, and then a numerical algorithm is used to find the design controller parameters such that all the roots of the closed-loop system are within ...

As the global Internet of things increasingly is popular with consumers and business environment, network flow management has become an important topic to optimize the performance on Internet of Things. The rigid existing Internet of things (IoT) architecture blocks current traffic management technology to provide a real differentiated service for large-scale IoT. Software-defined Internet of T...

An alternative adaptive-optic controller, using both flow control and a phase-lock-loop control strategy, has been designed to overcome bandwidth limitations inhibiting current adaptive-optic controllers. A discrete-vortex code and weakly compressible model were used to simulate high-speed shear layer adaptive-optic corrections based upon the proposed phase-lock-loop controller given a range of...

Software Defined Networking (SDN) is a networking architecture within the control centralized through software-based controller. Thus, being single point of attack makes it preferred target in case attack. Multi controller has been considered to reinforce plane. However, communication interface between security threat. We already propose dual architecture, one nominal which charge data plane co...

Abstract—This paper presents comparative study and implementation of Unified Power Quality Conditioner (UPQC) to eliminate harmonics and reactive power compensation in a single-phase to threephase converter system. The proposed configuration solves typical problems encountered in remote rural area applications, where only a single-phase supply is available and there is a demand for three-phase ...

This 'paper presents the development of a Proportional-Integral sliding mode controller for tracking problem of robot manipulators. A robust sliding mode controller is derived so that the actual trajectory tracks the desired trajectory as closely as possible despite the highly non-linear and coupled dynamics. The proposed controller is designed using the centralized and decentralized approaches...

We derive a nonlinear fuel optimal attitude control system (ACS) that drives the final state to the desired state according to a cost function that weights the final state angular error relative to the angular rate error. Control is achieved by allowing the pulsewidth-modulated (PWM) commands to begin and end anywhere within a control cycle, achieving a pulse width pulse time (PWPT) control. We...

Three-phase pwm voltage source inverters are widely employed in high performance ac drive system, active filters and uninterrupted power supply (UPS) etc.For these applications, the converter should provides good dynamic response. However the performance of the converter system largely depends on the accuracy of the applied current control strategy. The current controllers can be classified as ...
