“…Performance and robustness were tested on PMSM nonlinear model where nominal values of stator resistance were changed to two corner values of +/-40% nominal resistance. Assumptions from (Pohl, 2011) were confirmed and robust controller was able to provide stable control without sacrificing its performance, in fact the current closed loop as seen in figures 2 and 3 is not sensitive to 40% changes in stator speed at all (difference in response can be spotted on close up in Fig. 3).…”

This paper presents robustness analysis of linear parameter varying (LPV) controller for permanent magnet synchronous motor (PMSM). Robust controller was designed for synchronous motor in d-q rotating frame. Nonlinear equations of PMSM were rewritten to an LPV form with rotor speed as varying parameter. H ∞ LPV Controller was designed using Matlab Robust Control Toolbox. Desired shapes of sensitivity and complementary sensitivity functions were specified by weighting functions. Simulations with nonlinear model of PMSM were run with different sets of rotor resistance in order to verify robustness of resulting controller.

“…This method was successfully used in (Prempain, 2002) for control of an AC induction motor. Goal of this paper is to modify controller from (Pohl, 2011) to be usable in real world application and verify its performance and robustness for different sets of conditions.…”

This paper presents H 2 control based on linear parameter varying (LPV) systems for speed control of perma nent magnet synchronous motors(PMSMs). PMSMs model is rewritten in LPV systems which depend on online acces sible time varying parameters given by real time information. Since the PMSM nonlinear model can be transformed into LPV systems, we design H2 control with gain scheduling. The proposed method obtains both improvement of transient response in the speed control and reduction of energy consumption. Finally, simulation results are performed to validate that the proposed method has good performance of transient response and efficient energy consumption as compared with conventional field oriented control.

“…An alternative using a parameterisation of the LPV stabilising controller is used in [25] to regulate the angular speed. Applications for the permanent magnet synchronous motors (PMSMs) are discussed in [26, 27] where the LPV approach is used to develop a robust controller. In [27, 28], the LPV approach is proposed for the PMSM by using an output feedback scheme that yields high‐order controllers.…”

This study presents an optimal control strategy for the electronic interface of a wind energy conversion system based on a permanent magnet synchronous generator (PMSG). A linear optimal control is used on the grid side of the interface to ensure a proper power transfer and a linear parameter-varying (LPV) control on the machine side to cope with the wide operating conditions demanded by the wind turbine applications. The dynamics of a PMSG working in a variable speed wind turbine is affected by the rotational speed of the wind rotor. The LPV control uses the generator speed as a scheduling variable to adapt itself to different operating conditions. The proposed scheme results in a multi-variable self-scheduled controller with a PI structure similar to classical approaches. Thus, the control ensures performance and stability in all possible operating conditions whereas the implementation and the numerical stability are similar to previous schemes. The proposed control has been implemented in a test bench that includes a fully-rated back-to-back converter. The experimental results show a good performance in different scenarios in which the controller has to adapt itself to highly varying operating conditions.
