Summary: This paper presents a friction-and-load adaptive identification scheme based on a parallel-observer-based network with model compensation (POBN-MC) to optimize the control behavior of permanent-magnet synchronous motor drives. The scheme utilizes two novel observers to achieve the online adaptive identification of friction and load torque. The mapping relationship between nonlinear friction torque and rotor speed is determined in the first step, and the second step performs online observation matching the real-time operating conditions. The theoretical analyses, simulations, and experiments validate the feasibility and effectiveness of the proposed scheme.

Summary: Increasing the virtual inertia of the power system by using Virtual Synchronous Power (VSP) technology through the control of HVDC converter stations is a promising approach for integrating low-inertia renewable energy sources. This paper proposes a new evaluation framework that considers the impact of measurement period and various communication delays on the stability of the hybrid power system with VSP-based inertia emulation. A mitigation method through a modified Smith compensator is also proposed to reduce the impact of communication delays.

Summary: Two ADRC controllers considering speed measurement noise are proposed in this study, one based on ESO and the other based on PLLO. By using an integrator as the speed filter, the measured position can be directly used to observe speed and disturbance without affecting the systems' dynamic performance, and the PLLO-based ADRC system has a better ability to reject low-frequency disturbances. Experimental results confirm the effectiveness of the proposed methods.

Summary: A compound control method using an improved NFTSMC and disturbance observer compensation techniques has been developed to enhance the anti-disturbance performance of PMSM drives. The new NSMRL allows for chattering reduction on control output while maintaining high tracking performance, and the introduction of SMDO further improves the anti-disturbance performance. Both simulation and experimental results demonstrate better suppression of chattering effect, fast dynamic response, and disturbance rejection ability with the proposed control method.

Summary: An adaptive proportional-integral-resonant (PIR) controller with piecewise phase compensation is proposed to suppress the steady-state speed ripple of permanent magnet synchronous motor (PMSM) drive caused by current measurement error. The controller is designed to ensure stability at different speeds by restricting resonant gain and designing phase angle for robust vector margin in various speed ranges. Results from steady and transient experiments show that the proposed PIR controller effectively suppresses frequency-varying speed ripples due to current measurement error.
