“…12a ). He et al 51 attribute this effect to the fact that, in the early stages of curing, the pores within the mix can be used as an internal conductive pathway, which results in a higher electrical conductivity and in contrast a decreasing resistance. In this sense, with increasing curing age it can be observed that the values increase ( Fig.…”

“…It utilizes the characteristics of the rotor flux to design the sliding mode observer for estimating rotor position and speed. In the context of PMSM, scholars have conducted in-depth research and proposed various improved algorithms [7][8][9][10][11] to enhance control accuracy and disturbance rejection capabilities.…”

This paper proposes a control strategy that combines an improved flux-based sliding mode observer with a Radial Basis Function Proportional-Integral-Derivative (RBF-PID) controller for the control of Permanent Magnet Synchronous Motors (PMSM). The strategy aims to address the issues of electrical angle estimation errors and torque fluctuations in traditional sliding mode observer control. The improved sliding mode observer utilizes the flux model of the PMSM to enhance the accuracy of electrical angle estimation, thereby reducing the estimation errors and improving the control of the current loop and speed. The RBF-PID controller ensures system stability while achieving faster response and reduced torque fluctuations. Simulation and experimental results demonstrate that compared to traditional PI control and sliding mode observer control methods, the proposed strategy improves the performance of electrical angle estimation by 7.05% and reduces overshoot in the q-axis current by 28.6%, exhibiting better control performance and smaller errors.
