The design process of a rectangular waveguide pyramidal horn antenna is carried out. A mathematical design algorithm is developed and implemented in Matlab. The antenna model is built afterwards, accounting for the same computed parameters, with two different dedicated antenna design and simulation software packages: CST Microwave Studio and ANSYS HFSS. Both are based on the Finite Element Method...
Computational techniques conceived to improve the efficiency of PQ analysis of quasi-stationary signals acquired from the secondary winding of the excitation transformer in a power plant are addressed. Signals of 30 periods (SN) were analyzed. SN were polluted by white Gaussian noise and "arithmetic average" signals (AS) of one period length were computed for 2 reasons: (a) simpler noise...
A control strategy for positioning systems used in hail suppression is presented in this paper. The proposed position control solution is designed to obtain a precise control of the launch pad position over the azimuth and elevation, resulting in controlling a system with two degrees of freedom. The proposed strategy has been simulated starting from a permanent magnet synchronous motor that was modeled...
