Conventional localization of unmanned surface vehicle (USV) predominantly relies on a single integrated navigation system, typically comprising a global navigation satellite system (GNSS) and an inertial navigation system. However, the GNSS signals are vulnerable to external perturbations, which can substantially compromise the positioning accuracy. To achieve high-precision positioning of USV, t…
Accurate state estimation is essential for designing high-performance permanent magnet synchronous motor servo systems. However, the saturation of system input will severely undermine the consistency between control commands and actual inputs, leading to deviations between observer’s state prediction and actual system state, further deteriorating control performance. To address these issues, this…
The widespread deployment of power electronic devices in the grid has underscored the importance of real-time simulation. However, conventional L/C-based associated discrete circuit (L/C-ADC) model used for converter-level real-time simulation suffers from virtual power losses, thus limiting its applicability in high-frequency and large time step conditions. To address this issue, this article pr…
This work introduces an online virtual-physical system-based auto-tuning approach for initializing the parameters of direct adaptive controllers in grid-tied inverters with LCL filters. The method employs frequency-rich excitation signals to ensure sufficient parameter convergence prior to grid connection, effectively eliminating the need for empirical adjustments or offline optimization. A detai…
The series-connection of silicon carbide metal-oxide-semiconductor field-effect transistors (SiC MOSFETs) is essential for extending the blocking voltage capability in high-power applications, yet it inevitably suffers from dynamic voltage imbalance during switching transients. Dynamic voltage imbalance originates mainly from discrepancies in device intrinsic parasitic parameters as well as in ci…

Equipped with a fully clamped membrane and a closed-loop frequency-tracking system, the proposed microphone achieves acoustic signal detection in both infrasonic and audible frequency bands (with an experimentally verified bandwidth of 0.1 Hz–3.8 kHz). Key innovations include: 1) concurrent inf…
Nonlinear End-Effector Tracking Control With Almost Disturbance Decoupling for Five-DOF Tower Cranes
Tower cranes are crucial equipment for construction due to their high load-bearing capacity and efficiency in large-scale material handling. In practical applications, it is essential to ensure that payloads (end-effectors) are transported to desired positions efficiently and safely. However, tower cranes with underactuated structure often operate in complex environments and are subject to extern…
The nominal performance of mechanical systems is often degraded by unknown disturbances. A two-degree-of-freedom control structure can decouple nominal performance from disturbance rejection. However, perfect disturbance rejection is unattainable when the disturbance dynamic is unknown. In this work, we reveal an inherent tradeoff in disturbance estimation subject to tracking speed and tracking u…
This article introduces a dynamic impedance-aligned phase-angle compensation (DIA-PAC) for the targeted harmonic mitigation (PACTHM) control method, which is designed to enhance the performance of interior permanent-magnet synchronous motor (IPMSM) drives by effectively suppressing critical <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> …
The problem of global prescribed performance control (PPC) for the multi-input multi-output (MIMO) block-triangular systems with unknown nonlinearities and mismatched disturbances is investigated in this article. The design purposes lie in the independent prescribed settling times and the independent control gains. They cannot be fulfilled by the existing solutions and become more challenging und…
This article investigates the antidisturbance security control for dual-rate systems that are vulnerable to unknown disturbances and denial-of-service (DoS) attacks. The asynchronous conflict resulting from sampled signals at different rates is further exacerbated by cyberattacks, rendering information estimation considerably more difficult. A new state reconstruction technique, based on alternat…
This fusion approach enables robotic positioning without relying on global reference information, producing highly precise travel trajectories. To address measurement outliers, this article proposes a two-stage positioning method that combines robust filtering with offline optimization. First, the measurement noise distribution is modeled as a Student’s t-distribution, incorporating variational B…
Three-level (3L) inverters have seen widespread adoption in medium-to-high-voltage high-power drives compared to their two-level (2L) counterparts, owing to advantages such as reduced voltage stress on power devices and improved output waveform quality. Neutral-point voltage (NPV) balancing remains a critical issue in neutral-point-clamped (NPC) topologies, particularly in series-end winding (SEW…
In dynamic wireless power transfer systems, the large-air-gap magnetic field in couplers is characterized by a divergent and complex magnetic path and strong multi-variable coupling, thus resulting in a lack of concise and accurate theoretical design guidance. In response to these challenges, the research takes three-phase meander-type configuration as an example. By combining magnetic vector pot…
High-precision, high-reliability control of linear motors is crucial for intelligent manufacturing. However, existing methods are hindered by insufficient adaptive convergence, reliance on known uncertainty bounds, dependence on reference trajectory derivatives, and vulnerability to actuator faults. To overcome these limitations, a control scheme is proposed that synergistically integrates fixed-…
This article proposes a novel five-level power converter with only 12 switches and 12 diodes for a four-phase 8/6-pole switched reluctance motor (SRM), combined with a model predictive torque control (MPTC) strategy to suppress torque ripple. To overcome the high computational burden caused by the multilevel design, a candidate voltage vectors (CVVs) selection method is designed, reducing the num…
A practical finite-time neural pseudo inverse control (PFTNPIC) strategy is proposed to address the finite-time tracking control of fractional-order systems subject to asymmetric hysteresis and time-delay. To compensate for the asymmetric hysteresis effect, a novel pseudo inverse algorithm is developed based on the asymmetric shifted Prandtl–Ishlinskii model, thereby avoiding the need to construc…
Tightly coupled LiDAR-inertial odometer (LIO) often encounters robustness bottlenecks during violent motion due to two core issues: first, passive keyframe acceptance strategies fail to filter low-quality measurements introduced by abnormal motion; second, the absence of effective constraints leads to cumulative vertical drift on rough terrain. To address these challenges, this article introduces…
