This paper presents the modeling and parametric identification of a motor-generator set. Our aim is to obtain a model including the corresponding parameters for experimental research in power systems. The long term objective would be to have a turbine-generator emulator as an experimental tool for studying the transient behavior of a power system when small disturbances appear. The electric machines...
This paper presents the experimental implementation of a controller for the rotor position of a separately-excited DC Motor. The control law was designed by using a dynamic model for the motor and a dynamic model for the load torque. The torque model was proposed in order to improve the performance of the closed loop system. Discrete state feedback, discrete integrator and a discrete state observer...
This paper presents a topology for a PWM controlled three-phase voltage regulator which uses only two driven switches giving high reliability and making the switching stage simpler and cheaper compared with other available configurations. The proposed topology is suitable for voltage regulation on the distribution power system and able to regulate the steady state voltage and to reject voltage variations...
This paper describes the design and implementation of system to measure the heart frequency and rate based on a Doppler ultrasonic sensor, an analog filter and amplifier board, a frequency detecting circuit, an envelop detector and a microcontroller. The system is designed to measure the correct heart rate and give statistical information about the heart properly operation.
