“…For multi-motor drives, the drive system structure and control method depends on the application for which they are used and also on the performance, speed and accuracy needed from the drive system. For applications which do not demand a very high dynamic performance, a multi-motor, multi-inverter drive system using a modified V /f control strategy is described in (Iyer et al 2011). Another control method based on V /f strategy is given for a space vector modulated CSI drive in (Ma et al 2001) for medium voltage multi-motor drives.…”

Multi-machine, single-inverter induction motor drives are attractive in situations in which all machines are of similar ratings, and operate at approximately the same load torques. The advantages include small size compared to multi-inverter system, lower weight and overall cost. However, field oriented control of such drives is a challenge since no two motors will have exactly the same operating conditions at any time. In general, at least some motors in the system will operate away from perfect field orientation. It is therefore important to analyse their torque dynamics carefully. This paper discusses existing multi-machine field-oriented control methods, and analyses and compares them from the viewpoint of dynamic performance. For this, an analytical framework based on small-signal analysis is developed to compare multi-machine control methods. This analysis is verified by simulations and experiments.

“…The cost of the respective frequency converters is quite high, so one possible way to solve this problem is group capacity regulation [4]. The use of such a method can be found in various industries [5][6][7]. In the energy sector, this method is not common, so exploring its feasibility is of considerable interest.…”

The method of group capacity regulation of centrifugal mechanisms is proposed to solve the problem of increasing the energy efficiency of thermal power plant auxiliaries. The method is based on using a group frequency converter for basic capacity regulation of centrifugal mechanisms. Additional regulation is commonly carried out by throttling, bypassing or changing the guide vane opening angle.Analysis of auxiliary power consumption showed that due to ineffective regulation methods, the share of power consumption can reach 50 %. A mathematical model of the centrifugal mechanism that allows for studying various regulation methods is developed. The task of finding optimal control parameters for a group of centrifugal mechanisms that ensure power boiler operation is stated and solved. By the results obtained, it was determined that group capacity regulation of boiler draft mechanisms is most rational. For the feed pump, an individual variable-frequency drive shall be used.In contrast to the individual variable-frequency drive, the introduction of the group regulation method requires less investment. This method can significantly reduce the auxiliary power consumption of thermal power plants. The projected decrease in auxiliary power consumption is 10.7 %.The results show the high efficiency of the group capacity regulation of centrifugal mechanisms, so this method can become a promising direction in increasing the energy efficiency of thermal power plants

“…Several couplings by criteria merging for multi-machine, multiconverter systems are presented in [9]. Several control solutions have been presented: a modified V/f control strategy for a multi-machine multi-inverter drive system is given in [10] and fuzzy sliding and DTC-SVM control of multi induction motors connected in parallel are presented in [11,12]. Authors in [13] present an optimal predictive torque control of two parallel permanent magnet synchronous machines fed with a single inverter.…”

In this paper, a high-performance indirect field-oriented controlled dual Induction Motor (IM) drive fed by a single inverter using type-2 fuzzy logic control will be presented. At first, the mathematical model of the IM is implemented in the d-q reference frame. Then, the speed control of the Dual Induction Motor (DIM) operating in parallel configuration with Indirect Field Oriented Control (IFOC) using PI and type-2 Fuzzy Logic Controller (T2-FLC) will be presented. For the control of this system, a DC supply and a Space Vector Pulse Width Modulation (SVPWM) voltage source inverter are introduced with constant switching frequency. Also, the performance of T2-FLC, which is based on the IFOC, is tested and compared to those achieved using the PI controller. The simulation results demonstrate that the T2-FLC is more robust, efficient, and has superior dynamic performance for traction system applications.
