“…Various nonlinear control methods have been proposed to enhance the speed control performance of PMSMs in different aspects. These methods include sliding mode control [1,4,8,11,12], predictive control [13,14], backstepping control [15], adaptive control [15][16][17][18][19], H∞ control [20], automatic disturbance rejection control [21] and artificial intelligence incorporated controllers [12,22].…”

Permanent magnet synchronous motors (PMSMs) are known as highly efficient motors and are slowly replacing induction motors in diverse industries. PMSM systems are nonlinear and consist of time-varying parameters with high-order complex dynamics. High performance applications of PMSMs require their speed controllers to provide a fast response, precise tracking, small overshoot and strong disturbance rejection ability. Sliding mode control (SMC) is well known as a robust control method for systems with parameter variations and external disturbances. This paper investigates the current status of implementation of sliding mode control speed control of PMSMs. Our aim is to highlight various designs of sliding surface and composite controller designs with SMC implementation, which purpose is to improve controller’s robustness and/or to reduce SMC chattering. SMC enhancement using fractional order sliding surface design is elaborated and verified by simulation results presented. Remarkable features as well as disadvantages of previous works are summarized. Ideas on possible future works are also discussed, which emphasize on current gaps in this area of research.

“…In general, there typically exists a tradeoff between the control stability and adaptation margins. Thus, the adaptive switching gain (ρ) should be selected by carefully observing the trade-off between the transient response and control stability [25]. As can be seen in the proposed ASGT term (14), ξ is estimated by the sum of multiplying the absolute value of the sliding surface (σ ) by the ζ .…”

This paper designs an adaptive sliding mode speed controller (ASMSC) that can compensate for parameter uncertainty of an interior permanent magnet synchronous motor (IPMSM) drive. Unlike the previous control systems, the proposed ASMSC guarantees a precise speed tracking capability in the presence of severe parameter variations without accurate knowledge on the motor parameter values and uncertainty bounds. In particular, the proposed adaptive switching gain tuning (ASGT) term can effectively solve the excessive input energy consumption problem due to an unnecessarily overestimated switching gain. Next, the convergence and stability analysis are proven through a Lyapunov function. The feasibility of the proposed approach is verified via experimental results using a prototype IPMSM test bed with a TI TMS320F28335 digital signal processor. In this paper, the proposed SMSC is investigated with two control terms: without an ASGT term and with an ASGT term. In addition, the conventional proportional-integral speed controller and conventional linear matrix inequalities based sliding mode speed controller are chosen for the performance comparison. Finally, the proposed ASMSC can assure more robust and faster speed performances against the parameter uncertainty under three dynamic load conditions. INDEX TERMS Adaptive sliding mode speed controller (ASMSC), adaptive switching gain tuning (ASGT), interior permanent magnet synchronous motor (IPMSM), parameter uncertainty compensation.

“…Furthermore, to reach the dynamical and robustness performances required by the railway full-scale roller-rig, the motors are designed with a multilayer-rotor characterised by a high saliency ratio n and Interior Permanent Magnets (IPM). The IPM motors are controlled in real-time through vector control techniques; more particularly the vector control is a torque-controlled drive system in which the controller follows a desired torque [15,[25][26][27][28].…”

Nowadays, the longitudinal train dynamical behaviour is almost totally controlled by braking on board subsystems, such as Wheel Slide Protection (WSP) devices. The study and the development of these systems are fundamental for the vehicle safety, especially at high speeds and under degraded adhesion conditions. Traditionally, the performance of braking subsystems is tested on full-scale roller-rigs, to save time and to avoid expensive on-track tests. However, the study of the subsystem behaviour under degraded adhesion conditions on roller-rigs is still limited to few applications since high slidings among rollers and wheelsets generate wear of the rolling surfaces. This event is not acceptable because of the effects on the maintenance costs (the rollers have to be turned or substituted), on the system dynamical stability and on the safety. In this work the authors present an innovative Hardware In the Loop (HIL) approach for testing braking on board subsystems on full-scale roller-rigs. The new approach permits the reproduction on the rollerrig of a generic wheel-rail adhesion pattern and, in particular, of degraded adhesion conditions. The described strategy is the same implemented on the innovative full-scale roller-rig, recently built by Trenitalia and owned by SIMPRO, in the Railway Research and Approval Center of Firenze-Osmannoro (Italy). To validate the proposed approach, a complete model of the HIL system has been developed; the results provided by the simulation model have been compared to the experimental data provided by Trenitalia and relative to the on-track tests performed in Velim, Czech Republic, with a UIC-Z1 coach equipped with a fully-working WSP system. The complete model is based on the real characteristics of the components provided by Trenitalia. The preliminary validation performed with the HIL model highlighted the good performance of the HIL strategy in reproducing on the roller-rig the complex behaviour of the degraded adhesion during the braking of a railway vehicle. The next steps of the research activity will be the implementation both of the controller and the virtual vehicle model on the real Firenze-Osmannoro roller-rig.
