Closed Loop Continuous-time Foptd Identification Using Time-frequency Data from Relay Experiments
نویسندگان
چکیده
In this work the identification of first-order plus dead-time models from a relay experiment is considered. The relay excitation is applied to the closed-loop. Alternative techniques for identification are examined and simple algorithms are proposed for dealing with the dead-time. Simulation examples are used to illustrate the techniques.

Distance protection closed-loop testing using RTDS
This paper presents a distance protection test procedure by applying the Real-Time Digital Simulator (RTDS) of a power system. RTDS is a tool to design, develop, and test power-system protection. The RTDS enables real-time computation of electromagnetic phenomena with a calculation time step of even 50μs. The hardware allows the import and export of many signals from the simulator to an ext...
متن کاملAdaptive fuzzy pole placement for stabilization of non-linear systems
A new approach for pole placement of nonlinear systems using state feedback and fuzzy system is proposed. We use a new online fuzzy training method to identify and to obtain a fuzzy model for the unknown nonlinear system using only the system input and output. Then, we linearized this identified model at each sampling time to have an approximate linear time varying system. In order to stabilize...
متن کاملTime-Domain Fixed-Structure Closed-Loop Model Identification of an Unstable Multivariable Maglev Nanopositioning System
This paper presents improved empirical representations of a general class of open-loop unstable systems using closed-loop system identification. A multi-axis magnetic-levitation (maglev) nanopositioning system with an extended translational travel range is used as a test model to verify the closed-loop system-identification method presented in this paper. A closed-loop identification technique ...

متن کاملController Evaluation and Redesign Using Relay Experiments
In this paper it is presented a procedure for closed loop controller redesign using a relay based experiment. The present closed loop is evaluated in relation to a symmetrical optimum design. The loop gain is estimated at a few frequency points using an excitation derived from a relay experiment. The controller is redesigned to yield some stability margin using a controller procedure derived fr...
