“…ese drawbacks should have solutions by making an outer control loop in the IM drive, where the actual rotor speed ω r should be compared with a reference value ω ref , and hence, the error between these variables is generated [16][17][18]. is error is processed through a PI controller and a limiter to get the slip-speed command ω g .…”

In this paper, a new design of a real-time low-cost speed monitoring and closed-loop control of the three-phase induction motor (IM) is proposed. The proposed solution is based on a voltage/frequency (V/F) control approach and a PI antiwindup regulator. It uses the Waijung Blockset which considerably alleviates the heaviness and the difficulty of the microcontroller’s programming task incessantly crucial for the implementation and the management of such complex applications. Indeed, it automatically generates C codes for many types of microcontrollers like the STM32F4 family, also used in this application. Furthermore, it offers a cost-effective design reducing the system components and increasing its efficiency. To prove the efficiency of the suggested design, not only simulation results are carried out for a wide range of variations in load and reference speed but also experimental assessment. The real-time closed-loop control performances are proved using the aMG SQLite Data Server via the UART port board, whereas Waijung WebPage Designer (W2D) is used for the web monitoring task. Experimental results prove the accuracy and robustness of the proposed solution.

“…Since the system generates only instantaneous values of the current moduli, and the instantaneous value of the stator voltage may differ from the set value due to external disturbances, the stability of the system is determined not by the value of the load angle θ, but by the nature of the system's response to external disturbances. The stability criterion here is the same as for a conventional implicit-pole synchronous machine: with a load surge, the motor torque must increase, compensating for the load torque, in this case the mode is considered stable [15][16][17].…”

Frequency Control System for a Synchronized Asynchronous Electric Drive

2020

Considering the problem of energy saving at industrial enterprises, attention should be paid to the fact that about 70 ... 80% of all electric motors are asynchronous, and most of them are installed in unregulated drives. Most of these electric drives are equipped with asynchronous electric motors with a squirrel-cage rotor (AM SC). Energy saving problem in such cases can be solved by using a frequency converter (FC), however, all FC models are intended for AM SCs, while until the mid-90s the most common variable AC drives were electric drives equipped by an asynchronous motor with a phase rotor (AD PR) as they provided easy speed regulation through the rotor circuit. Such drives are usually used in hoisting and transport machines (conveyors, cranes, etc.). Direct transfer of the abovementioned drives to frequency-controlled mode is quite complicated due to the fact that standard inverters are designed to work with AM SCs having no phase rotor winding, and whose short-circuiting leads to additional electromagnetic losses in comparison with AM SC. An upcoming engineering trend is the development and research of synchronized AM control systems.

Analysis of the effectiveness of using state observers in the control system of the traveling mechanism of the bridge crane trolley

et al. 2020

This article discusses the frequency control systems of an asynchronous electric drive with various types of observers that are promising for the movement mechanism of the bridge crane trolley. As a result of the analysis of existing control systems for asynchronous motors, it was revealed that the most relevant for use at the object under consideration is a system with direct torque control. To improve the classical control system, it is proposed to introduce a state observer into it. Sensorless control systems, in comparison with other systems, make it possible to reduce the dimensions of both a separate mechanism and the device as a whole, and reduce its cost. The use of observers leads to an increase in the reliability of an object without complicating its design. For the functioning of systems of this type, only data from the current and voltage sensors built into the frequency converter are used.
