Output-Feedback Multi-Loop Positioning Technique via Dual Motor Synchronization Approach for Elevator System Applications

A New approach for Design Technique of Multi-Rate Output Feedback Control using PID Controller

A new approach for designing a multirate output feedback control system using PID Controller, where the update interval of the control input is an integer multiple of the sampling interval of the plant output. The proposed method is designed by extending a conventional multirate output feedback control using the latest information of a plant. Hence, the proposed method can improve the control p...

Multi-Objective Output-Feedback Control via LMI Optimization

This paper presents an overview of a linear matrix inequality (LMI) approach to the multiobjective synthesis of linear output-feedback controllers. The design objectives can be a mix of H1 performance, H2 performance, passivity, asymptotic disturbance rejection, time-domain constraints, and constraints on the closed-loop pole location. In addition, these objectives can be specified on different...

Dual Phase Detector Based Delay Locked Loop for High Speed Applications

In this paper a new architecture for delay locked loops will be presented.  One of problems in phase-frequency detectors (PFD) is static phase offset or reset path delay. The proposed structure decreases the jitter resulted from PFD by switching two PFDs. In this new architecture, a conventional PFD is used before locking of DLL to decrease the amount of phase difference between input and outpu...

Design of Decentralized Power System Stabilizer for Multi-Machine Power System using Fast Output Sampling Feedback Technique

Abstract—Power System Stabilizer (PSS) are added to excitation system to enhance the damping of electric power system during low frequency oscillations. Design of decentralized PSS for 4 machines with 10 buses using fast output sampling feedback is proposed. The nonlinear model of multi-machine system is linearized and linear state space model is obtained. A stabilizing state feedback gain is o...
