In this paper a simple load power estimator for the three-phase quasi-direct acac converter system is reported. Since the ac-ac converter control by means of pulsewidth modulation (PWM) is based on the power balance ...

This paper shows the topology of the hybrid grid-connected power system and the performances of the front-end three-phase power inverter. The renewable sources of the hybrid power system consist of a solid oxide fuel cell ...

In this paper an alternative method to the classical control of the induction motor drive system is proposed. More exactly, a model predictive control (MPC) for the rotor speed of the induction motor is presented. The ...

This paper presents a method for calculating the reference currents needed for the command of an active filter. By using the Discrete Wavelet Transform (DWT) the high-frequency components of the currents are eliminated. ...

In the paper is developed a new control strategy for the adjustable speed drives. The strategy consists in the energetic optimal control of the dynamic regimes as starting, stopping and reversing. The main developed ...

In this paper the optimal electrical drive development system is presented. It consists of both electrical drive types: DC and AC. In order to implement the optimal control for AC drive system an Altivar 71 inverter, a ...

This paper is concerned with the performance comparison of Sliding Mode Controller and conventional PID Controller for the control of DC Motor. The DC motor can be modeled as a linear time invariant single input single ...

The quality of the electrical current becomes a major concern. The proliferation of the power electronic converters, which are used extensively to control electrical apparatus in industrial and commercial applications (dc ...

Model reference adaptive control (MRAC) of three-phase induction machine in rotor field coordinated is proposed in this paper. The proposed adaptive structure is in direct form, such that the controller parameters are ...

This main objective of the paper is to stabilize an electric vehicle in optimal manner to a step lane change maneuver. To define the mathematical model of the vehicle, the rigid body moving on a plane is taken into ...
