The kagome superconductor CsV_(3)Sb_(5) has attracted widespread attention due to its rich correlated electron states including superconductivity, charge density wave(CDW), nematicity, and pair density wave. Notably, the modulation of the intertwined electronic orders by the chemical doping is significant to illuminate the cooperation/competition between multiple phases in kagome superconductors. In this study, we have synthesized a series of tantalum-substituted Cs(V_(1-x)Ta_(x))_(3)Sb_(5) by a modified self-flux method. Electrical transport measurements reveal that CDW is suppressed gradually and becomes undetectable as the doping content of x is over 0.07. Concurrently, the superconductivity is enhanced monotonically from T_(c) ~ 2.8 K at x = 0 to 5.2 K at x = 0.12. Intriguingly, in the absence of CDW, Cs(V_(1-x)Ta_(x))_(3)Sb_(5)(x = 0.12) crystals exhibit a pronounced two-fold symmetry of the in-plane angular-dependent magnetoresistance(AMR) in the superconducting state, indicating the anisotropic superconducting properties in the Cs(V_(1-x)Ta_(x))_(3)Sb_(5). Our findings demonstrate that Cs(V_(1-x)Ta_(x))_(3)Sb_(5) with the non-trivial band topology is an excellent platform to explore the superconductivity mechanism and intertwined electronic orders in quantum materials.

喷墨印花设备的伺服驱动系统的控制精度和稳定性直接决定了喷墨印花的精度和效率,因此由喷墨印花伺服系统驱动的喷印小车必须满足多级变速、停车锁定等要求。然而,传统的PID控制器难以整定PID参数。将专家PID控制算法和分段函数进行线性拟合,根据喷印小车的运动状态实时整定PID参数,由此设计的伺服控制系统满足了喷墨印花过程中小车的运动需求。实际的试验结果和电动机输出表明,本控制器满足了喷印过程中对电动机转速和位置锁定的需求。
