“…In addition, progress in power electronics allows one to obtain reliable and flexible supply sources. These two factors, combined with industrial demand for high-performance motion systems, justify the development of new control structures for electrical drives [1][2][3][4][5][6][7][8][9][10][11].…”

This paper investigates the application of a novel Model Predictive Control structure for the drive system with an induction motor. The proposed controller has a cascade-free structure that consists of a vector of electromagnetics (torque, flux) and mechanical (speed) states of the system. The long-horizon version of the MPC is investigated in the paper. In order to reduce the computational complexity of the algorithm, an explicit version is applied. The influence of different factors (length of the control and predictive horizon, values of weights) on the performance of the drive system is investigated. The effectiveness of the proposed approach is validated by some experimental tests.

“…In typical realization, the sensorless operation in speed control of PMSM drive may be achieved in field-oriented control (FOC) just by elimination of the position sensor, and use of a position estimator, even in more complex drives, e.g. fed by sinusoidal filter (Urbanski, 2013), or use the open loop mode for simple drives (Brock and Pajchrowski, 2013), or use the direct torque control (DTC) method (Ahmed Adam and Gulez, 2009). However, the speed calculation directly from estimated position value is not so trivial in the case of low-speed range of operation (Raute et al, 2007(Raute et al, , 2011Gu et al, 2009), or in a case of high-dynamic drive (Hunter, 2011), because it is assumed that the back EMF estimation does not have sufficient accuracy at lower speed range, and there is a possibility of the excitation oscillations by the estimator.…”

Purpose -The purpose of this paper is to develop the Permanent Magnet Synchronous Motors drive which has possibility to work in sensorless mode at low speed based on back EMFs estimation. Design/methodology/approach -Estimation uses modified Luenberger observer and the preprocessing of the EMFs before calculating the speed, using derivative and the Kalman filter (KF) to obtain smooth waveform of the estimated speed. This modification is needed because of the nonlinear change of the estimated back EMFs amplitude as a function of speed, in low-speed range. Findings -How to use back EMF observer to estimate a speed in the low-speed range was found in the course of the work. Simple and effective algorithm uses KF and can work even with a relatively big deformation of the estimated back EMF. Practical implications -Such sensorless drive may be used in low-cost constant or variable speed drive in domestic use or industrial application. Such drive may work properly where there is no initial load torque and the sign of the speed does not change. Originality/value -Presented results challenge the view that at low-speed range (not the standstill), the back EMF-based method of position estimation is very difficult or impossible. However, the problem lays in proper speed estimation, not the position estimation.

“…For the drive with dc motor model reference linear adaptive speed controller is designed in [4] to drive the output speed at any load to the maximum efficiency by controlling motor excitation current. A new energy saving control strategy based on sensorless flow rate estimation and pump operation analysis for variable speed controlled parallel pumps is described in [5].…”

Speed and position controller respecting principles of energy optimal control for the drives with permanent magnet synchronous motor and time varying load torque are developed as a contribution to the energy saving and environmental protection. Two approaches to the energy saving controller design are analyzed and compared. The first one is strictly based on energy optimal control theory and derives analytical solutions of the control problem. The second approach for comparison presents approximated solution for the drive’s position controller when the optimal speed trajectory is modified to trapezoidal profile. Results are verified by simulation.
