This paper is concerned with the design and implementation of a robust position backstepping tracking controller for a permanent magnet synchronous motor (PMSM). The information on the angular position and velocity, provided by a classical resolver-to-digital converter, additionally employs a phase lock loop (PLL) circuit. A backstepping control law is designed from the input-output linearization of the PMSM model, written in d-q coordinates. This controller is adapted via the online estimation of the unknown load torque and friction effects. A linear extended state observer is devised for this purpose, thus ensuring high closed-loop performance of the motor trajectory tracking task. An input-state stability analysis of the entire system is also provided. Cosimulation via the MATLAB/Simulink-PSIM package, including realistic measurement disturbances, is used to investigate the stability and accuracy of the proposed control algorithm. Experimental results are provided. Index Terms-Input-state stability (ISS), load torque linear extended state observer (LESO), permanent magnet synchronous motor (PMSM), position backstepping tracking controller. I. INTRODUCTIONP ERMANENT magnet synchronous motors (PMSMs) exhibit a remarkable torque density and the highest efficiency among several other electrical machines [2]. Given these advantages, the PMSMs have extended their applications in machine tools, robotics, automotive applications, electrical mobility, electric aircraft, renewable power generation, and home appliances [2]. The conventional proportional-integralderivative (PID) control method still remains popular, thanks to its simplicity and its overall good performance at some operating points [1]. However, the PMSM is a nonlinear system with nonmeasurable endogenous and exogenous unknown disturbances [15]. It is therefore not easy to always obtain an excellent performance over the full range of operation, when classical linear feedback control methods are used [18], [29]. ).

Bidirectional Tracking Robust Controls for a DC/DC Buck Converter‐DC Motor System

et al. 2018

Two differential flatness-based bidirectional tracking robust controls for a DC/DC Buck converter-DC motor system are designed. To achieve such a bidirectional tracking, an inverter is used in the system. First control considers the complete dynamics of the system, that is, it considers the DC/DC Buck converter-inverter-DC motor connection as a whole. Whereas the second separates the dynamics of the Buck converter from the one of the inverter-DC motor, so that a hierarchical controller is generated. The experimental implementation of both controls is performed via MATLAB-Simulink and a DS1104 board in a built prototype of the DC/DC Buck converter-inverter-DC motor connection. Controls show a good performance even when system parameters are subjected to abrupt uncertainties. Thus, robustness of such controls is verified.

“…When we know only the system order the ADRC does not consider the uncertainty explicitly, and views both structured and unstructured uncertainties as generalized disturbances. This feature found wide application in industry, even though its theoretical justification was lagging behind for quite some time .…”

The extended state observer (ESO) based controller has been used successfully with integer-order systems involving large uncertainties. In this paper, the robust control of uncertain multi-order fractional-order (FO) systems based on ESO is investigated. First, we transform the multi-order FO system into an equivalent system in the form of a same-order state-space equation. Then, the ESO for the new system is established for estimating both the state and the total disturbance. Sufficient conditions for bounded-input and bounded-output stability are derived, and the asymptotic stability of the closed loop system is analyzed, based on whether the states are available or not. Finally, numerical simulations are presented to demonstrate the validity and feasibility of the proposed methodology.
