摘要：This article presents properties of a follow–up system executing ship’s rudder deflection using a constant delivery hydraulic pump.Furthermore,a solution is discussed which increases static and dynamic accuracy of such a system using the rudder angular velocity signal.This signal has been used for changing the level of a three–position controller insensitivity.The paper also shows the method of determination of the function describing variations of dead–zone width of the three–point controller.Two kinds of such function are shown,namely linear and quadratic.A computer model was prepared in MATLAB–Simulink environment,showing the operation of the system with correction of error signal,which carries out given by function variations of points of switching.Also included are the simulation results of the described solution,indicating a significant enhancement of accuracy of rudder angle control process for the steady state as well as during transients.
其他摘要：Tujuan dari penelitian ini adalah untuk menganalisis pengaruh keputusan pembelaian produk keputusan di Indonesian.Variables diidentifikasi dalam survei adalah dukungan Selebriti dan Keputusan Pembelian.Produk responden konsumen di Indonesia.Penelitian ini dilakukan secara online tersebar di seluruh wilayah Indonesia.Data dikumpulkan dengan kuesioner dibagikan langsung kepada responden,data yang digunakan adalah data primer yaitu dengan menyebarkan kuesioner kepada 300 responden.Teknik sampling yang digunakan langsung non–probability sampling data purposive sampling.Hasil penelitian menunjukkan bahwa pengaruh positif dukungan selebriti terhadap Keputusan Pembelian.Semua indikator dukungan selebriti secara simultan dapat mempengaruhi keputusan pembelian..
