“…This is because Simulink automatically adds interaction forces between the individual blocks of the model. In the SimInTech model, these interactions are absent, but they can be taken into account by complicating the original mathematical model [51,[66][67][68][69][70].…”

A six-legged spider robot is a complex object from the point of view of the problem of synthesizing a system for controlling its movement. To synthesize an advanced control system for such a robot, which must solve non-trivial problems of overcoming obstacles, functioning under conditions of external disturbances, etc., we first solve the problem of synthesizing an information model of the object, on the basis of which its control system will subsequently be built.The paper compares two methods for synthesizing the information model of a six-legged spider-robot. In the first method, an information model is automatically synthesized from a CAD model of a spider-robot in a MATLAB-based graphical programming environment Simulink. In the second method, the information model is synthesized in the environment of dynamic modeling of technical systems SimInTech on the basis of a system of differential equations in the Cauchy form. Control loops and external influences are added to the information models synthesized in each of the modeling environments. The study showed that each of the resulting models has both its own individual advantages and disadvantages. They are mainly related to taking into account the mutual influence of various blocks of models on each other. It is shown that, in the end, the two models complement each other and make it possible to obtain an advanced basis for further synthesis of the motion control system.The results obtained in this work make it possible to use information models as a basis for the development of a control system for a physical model of a six-legged spider-robot, printed on a 3D printer and assembled on the basis of the Arduino hardware platform.

“…Для применения оптической системы на судах необходимо выполнить следующие требования: низкая стоимость, высокая точность (обнаружение небольшого сдвига длины волны) и широкий диапазон измерения. При обзоре литературы [1][2][3][4] были выявлены исследования, проводимые для контроля деформации с помощью метода лазерной синхронизации Паунда -Древер -Холла (метода улучшения стабильности длины волны лазера с течением времени). Используя этот метод, можно разработать высокоточную измерительную систему, применяющую оптоволоконный датчик в системах контроля крутящего момента.…”

The article considers the procedure of torque control, which is very popular in a wide variety of industries with many design features. In marine power engineering the problems of determining the forces, torque on the shaft and power are solved by means of torsiometers with torque sensors. The most widely used torque sensors are of capacitive, induction, strain gauge and photoelectric types. It has been stated that there are limitations in the process of torque control due to the susceptibility of systems to the electromagnetic interference, lack of a high degree of protection for electrical equipment and necessary recalibration. Fiber optic systems have found application in torque measurement systems in the oil and gas and aerospace industries. The use of such systems on ships is more expensive in comparison with the technologies used today, for example, the systems based on strain gauges. It has been proposed to use an inexpensive optical measuring system based on the Pound-Drever-Hall technique with using a foil-clad strain gauge and an aluminum torsion rod. There has been illustrated the system of torque control, the phase graphs for the Fabry-Perot resonator and the graph of the resonator transmission spectrum are presented, the reflection coefficient value is given. A method for measuring the phase of a reflected beam from a Fabry-Perot resonator is being considered, the injection current of a laser is modulated by means of an electric oscillator to generate side stripes in the electric field of a laser beam. The carried out studies and calculations contribute to improving the reliability of the coastal power system; the possibility of their use in marine electrical systems has been proved.

The article considers application of fiber optic devices in many devices due to their small size and high accuracy. The new fiber optic devices are equipped with a Slab Coupled Fiber (SCF) system. The SCF method uses resonant coupling between an optical fiber and a plate waveguide to create an intra-fiber device. Devices manufactured with this technology consist of polarizers, filters and sensors. Fiber optic systems have been used in torque measurement systems in the oil and gas industry and in aerospace industry. Using this system on ships is more expensive in comparison with the technologies based on strain gauges. There is offered using inexpensive optical measuring system with plate optical sensors. SCF devices use D-shaped fiber as a platform. Plate optical sensor (SCOS) devices are based on the use of an electro-optical sensor. Today, a D-fiber coupled magnetic field sensor has been developed. The device combines a magneto-optical plate waveguide with a D-fiber to measure magnetic fields. The plate coupled magneto-optical sensor (MO-SCOS) measures magnetic fields up to 2 A/m. Due to its short length the sensor can display fields with a spatial resolution of 1 mm.
