An Optimization-Based Method to Determine the Hydraulic Amplifier Piston Position

Hydraulic systems are one of the most popular types of drives. They are mostly used in industry and mobile applications.Wherever high forces are required, such as in the machinery and power industry, transportation or emergency equipment, hydraulicsystems are utilized. One of the hydraulic system components facing energy management and power consumption issues is a hydraulicpressure amplifier. This device, using the switching control technique, generates high oil pressure which results in obtaining high forcewhen it is required. This paper covers hydraulic pressure amplifier work principles and introduces a method to determine the positionof the working piston in such devices. Based on the examination results, the position changing algorithm was implemented utilizing thegradient descent optimization method.
