In this study, the e ff ects in terms of electric stress of composite voltages on a high-voltage disconnector were investigated. The main purpose of this study is to determine and evaluate the e ff ects of the conditions that may occur in real working conditions but out of the type tests. As for the disconnector model, one phase of a center-break disconnector was considered. In order to examine the e ff ects of composite voltages on high-voltage disconnectors, a model is de fi ned in the Comsol Multiphysics program. Di ff erent types of voltages such as operating voltage, 50 Hz test voltage, lightning impulse voltage, and composite voltage, were applied to the 170 kV disconnector model separately. After applying a composite voltage consisting of power frequency voltage and lightning impulse voltage to the disconnector, electric potential and electric fi eld distributions were obtained. It has been observed that the maximum electric potential and the maximum electric fi eld strength values on the disconnector are higher when composite voltage is applied than when non-composite voltage is applied to the disconnector. It is observed that the intensity of the electric fi eld lines increases near the contacts of the current-carrying arm and the main contacts of the disconnector.

An approach to obtain e ff ective control of insertion loss (IL) in wideband substrateintegrated waveguide (SIW) band-pass fi lter with several tapered Iris con fi gurations is presented in this paper. Several iris con fi gurations and iris parameters have been minutely studied and e ff ective postulates have been provided for accurate design of fi lters with low IL throughout the transmission bandwidth. Basic structure is designed over a substrate with dielectric constant 3.2 and material thickness of 30 mils. The structures are then successfully modi fi ed into a band-pass fi lter with its pass band in Ku bands with minimal IL using waveguide iris method. The technique e ff ectively serves the purpose to achieve greater control over the IL and isolation. Maximum IL of 2 dB is reduced by 1.5 dB and close to 0.5 dB IL is obtained in the fi nal con fi guration using the tapering technique. Proposed techniques are supported with theoretical explanations. All designs are fabricated, and measured results are found to validate the concept produced in this paper. The study provides a direct solution to the SIW Iris fi lter design engineers considering all major parameters necessary foriI ndust rial/ scien ti fi c productions.
本文介绍了在宽带基片集成波导（SIW）带通滤波器中使用几种锥形光圈结构有效控制插入损耗（IL）的方法。本文对几种虹膜结构和虹膜参数进行了深入研究，并为准确设计在整个传输带宽内具有低 IL 的滤波器提供了有效假设。基本结构是在介电常数为 3.2、材料厚度为 30 密耳的基板上设计的。然后，利用波导光圈法成功地将该结构修改为带通滤波器，其通频带在 Ku 波段，IL 最小。该技术有效地实现了对 IL 和隔离度的更大控制。使用锥形技术，2 dB 的最大 IL 降低了 1.5 dB，最终配置的 IL 接近 0.5 dB。提出的技术有理论依据。所有设计均已制作完成，测量结果验证了本文提出的概念。这项研究为 SIW 虹膜滤波器设计工程师提供了直接的解决方案，考虑到了工业/科学生产所需的所有主要参数。

In this paper, an adaptive predictive control for controlling and stabilizing fractional order chaotic systems around the equilibrium point is provided. The stability of fractional order chaotic systems around equilibrium points in the presence of parameter uncertainty has been demonstrated using Lyapunov's stability theorem. In addition, the uncertain parameters of fractional order chaotic systems are calculated using appropriate adaptive methods based on the proposed predictive controller structure. Rossler and Chen systems were considered to numerical simulations. The results demonstrated the adaptive predictive control method's usefulness and performance
