Introduction to Low-potential Electrotechnical System of Power Efficient Conversion of Electrical Energy Using SMPS
(2015)
The negative impact generated from conventional energy sources has been continually increasing over the last century, and new types of energy sources must be found. All energy sources can be divided into two types: ...
Simple dynamic energy efficient field oriented control in induction motors
(2015)
The current paper discusses the optimal choice of a filter time constant for filtering the steady state flux reference in an energy efficient control strategy for changing load torques. It is shown that by appropriately ...
Investigation of the Process Parameters Influence on the Energy Efficiency of an Induction Motor under Model Predictive Control GRAMPC
(2017)
This paper presents the implementation of the nonlinear gradient based model predictive control (MPC)
software GRAMPC (GRAdient based MPC) for the energy efficient control of three-phase induction motor drives. GRAMPC is ...
Power losses minimization and energy accounts in induction motors with nonstationary loads
(2019)
The main objective of this paper is to analyze domestic and foreign experience regarding the simultaneous electromagnetic and electromechanical transients in an electromechanical system with an electric motor based on an ...
Control law of motion control of a delta robot adapted to digital systems with not high performance
(2018)
The delta robot is a parallel robot, which means there is more than one kinematic chain from the base to the actuator of the robot. It has three translational and one rotational degree of freedom. The basic idea is the use ...
Optimal Field-Oriented Control of an Induction Motor for Loss Minimization in Dynamic Operation
(2019)
The problem of minimizing the power consumption of an induction motor (IM) operating from a
frequency converter in vector control mode is considered. This contribution presents an application of a ...
