“…Moreover, the speed sensor increases the cost of the induction motor drives. To eliminate the speed sensor, the calculation of the speed may be based on the coupled circuit equations of the motor [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34]. The following explanation and analysis of the stability of the Model Reference Adaptive System (MRAS) speed estimator.…”

Robust Speed Controller Design Using H_infinity Theory for High-Performance Sensorless Induction Motor Drives

In this paper, a robust speed control scheme for high dynamic performance sensorless induction motor drives based on the H_infinity (H) theory has been presented and analyzed. The proposed controller is robust against system parameter variations and achieves good dynamic performance. In addition, it rejects disturbances well and can minimize system noise. The H controller design has a standard form that emphasizes the selection of the weighting functions that achieve the robustness and performance goals of motor drives in a wide range of operating conditions. Moreover, for eliminating the speed encoder—which increases the cost and decreases the overall system reliability—a motor speed estimation using a Model Reference Adaptive System (MRAS) is included. The estimated speed of the motor is used as a control signal in a sensor-free field-oriented control mechanism for induction motor drives. To explore the effectiveness of the suggested robust control scheme, the performance of the control scheme with the proposed controllers at different operating conditions such as a sudden change of the speed command/load torque disturbance is compared with that when using a classical controller. Experimental and simulation results demonstrate that the presented control scheme with the H controller and MRAS speed estimator has a reasonable estimated motor speed accuracy and a good dynamic performance.

“…During the twentieth century, speed sensorless techniques have become more sophisticated, efficient, effective, and have achieved good results. [12][13][14][15]. In recent years, research on power electronics and signal processors has grown rapidly; for this reason, current sensing techniques with a reduced number of sensors has attracted much attention from the research community, in order to avoid faults caused by current sensors, improve the sensor fault tolerance of the system, enhance the reliability, reduce the costs of industrial applications, decrease the complexity of the systems, simplify the implementation, and minimize the volume of the systems as much as possible.…”

High-performance vector control without AC phase current sensors for induction motor drives: Simulation and real-time implementation

The main purpose of this paper is to develop a high-level performance, and low-cost current sensorless control strategy for Induction Motor (IM) drives. Therefore, a new phase-current regeneration method, for current sensorless vector control in induction motor drives is introduced. The idea is based on the reconfiguration of the Luenberger adaptive observer for currents estimation, using the information provided by the dc-link voltage sensor. The basis of the proposed control and the theoretical study of the modified adaptive observer are presented. Several simulation and experimental tests were performed on an induction motor of 1.1 kW working under different operating conditions. The obtained results prove and testify the relevance, workability, and practicability of the suggested currents sensorless vector control strategy.

“…Consequently, AGs are capable of operating only in systems in which there are sources of reactive power. These can be either a system in which the source of reactive power is a synchronous machine, which also performs the function of a synchronous compensator, or a static source of reactive power [1][2][3][4][5][6].…”

The article describes the use of asynchronous machines in generator mode to provide power to threephase consumers, as well as the features of autonomous and parallel operation of an asynchronous generator with an infinite power network. The use of static sources of reactive power allows widespread introduction of an asynchronous generator in the electric power system as a reliable source of active power.
