“…To authenticate the superior performance in stable control of autonomous system, more practical tests should be carried out in the same conditions. Traditionally, to drive the autonomous vehicle stably, the parametric curves are usually generated by general-purpose micro-controller unit (MCU) [57,58]. In detail, the polynomial functions are deployed to drive the autonomous system in two cases: our approach and conventional method.…”

This study addresses the challenge of motion control in autonomousvehicles through the introduction of a novel profile generation design. Specifically,autonomous vehicles often contend with uncertain factors and physicallimitations within their operational environments, such as abrupt changes inacceleration or intricate parametric motion profiles. To tackle this problem, afiltering technique for motion profile generation is proposed, leveraging ahardware programming language as its foundation. The investigation begins byanalyzing the specific structure of the mobile platform, which includes twoactive side wheels, two passive rear wheels, a high load capacity, and adifferential drive mode. Building upon this theoretical basis, the proposedfiltering technique is introduced to attain smooth motion profiles and optimizetiming. Furthermore, the study suggests the use of FPGA (Field ProgrammableGate Array) acceleration to expedite these computations for swift motionprocessing. To validate the efficacy of the proposed method, both the mobilevehicle and the load are simulated as a one‐axis linear ball‐screw system withan aluminum ruler. The experimental results unequivocally demonstrate theeffectiveness, feasibility, and applicability of the proposed approach across avariety of industrial solutions.

“…Sweeping the applied microwave frequency leads to the optically detected magnetic resonance (ODMR) 26 spectrum in Figure 3C, which corresponds to the transition between the ground‐state |0> and | ± 1>. Generally, the magnetic field sensitivity using the ODMR technique can be determined by 14,23 :

η = P_{F} \frac{2 ℏ}{g μ_{B}} \frac{1}{α \sqrt{β T^{*}}}

where P F is a numerical factor determined by the profile of the NV resonance, and P F ≈ 0.70 for a Gaussian lineshape, P F ≈ 0.77 for a Lorentzian lineshape; ℏ is the Planck constant; g is the Lande factor; μ B is the Bohr magneton. The variable α is resonance contrast; β is the number of photons collected per measurement; T* is the NV spin dephasing time.…”

In diamond nitrogen-vacancy (NV) magnetic field sensors, microwave delivery and irradiation with efficient, uniform, and wide dynamic range are necessary to achieve more accurate measurement and higher sensitivity. Here, we report on the development of a triple-mode broadband waveguide bandpass filter (BPF), which uses a high-Q metallic cavity to transfer the microwave and excite the diamond NV spin ensembles. This BPF provides a more efficient, low-loss, uniform, and broadband microwave signal, as well as a closed space for the NV-quantum sensor. The developed BPF exhibits a large fractional bandwidth (FBW) of 34.8% with a center frequency of 2.87 GHz, and this leads to improve the measurable static magnetic field range up to 5.36 Â 10 À2 T.Experimental results show that the sensitivity is improved to 14.67 μT/Hz 1/2 compared to the patch antenna of 188.49 μT/Hz 1/2 , that is usually used in the conventional diamond NV-based quantum sensors.
