Automatic Removal

The roller and sieve machines most commonly used in Russia for the post-harvest processing of root and tuber crops and onions have a number of disadvantages, the main one being a decrease in the quality of sorting due to the contamination of working bodies, which increases the quantity of losses during sorting and storage. To obtain high-quality competitive production, it is necessary to combine a number of technological operations during the sorting process, such as dividing the material into classes and fractions by quality and size, as well as identifying and removing damaged products. In order to improve the quality of sorting of root tubers and onions by size, it is necessary to ensure the development of an automatic control system for operating and technological parameters, the use of which will eliminate manual sorting on bulkhead tables in post-harvest processing. To fulfill these conditions, the developed automatic control system must have the ability to identify the material on the sorting surface, taking into account external damage and ensuring the automatic removal of impurities. In this study, the highest sorting accuracy of tubers (of more than 91%) was achieved with a forward speed of 1.2 m/s for the conveyor of the sorting table, with damage to 2.2% of the tubers, which meets the agrotechnical requirements for post-harvest processing. This feature distinguishes the developed device from similar ones.

Automatic Removal

The paper presents a concept of automatic control system recovering an aircraft from the spin using fuzzy logic controller. Control system causing: stall, spin, spin recovery, dive recovery and switching on classic heading and altitude autopilots, was created in Matlab – Simulink software, which was connected to the flight simulator X-Plane. During tests developed control algorithms were checked and tuned. At the end graphs of flight parameters recorded during simulation were analyzed, and properties of designed control system were evaluated. Particular attention was paid to the design of a fuzzy logic controller stopping autorotation of the aircraft. On the output it controlled the position of the rudder, while on input it received a signal being a function of the angular velocity of the aircraft.

According to the automatic control system of pneumatic AMT clutch, this paper proposes a novel PID control based on logical switch of clutch engagement index. The PWM control is used to make a control for the solenoid valve. And a controller is established by this control algorithm. The automatic control system of pneumatic AMT clutches modeling using the AMEsim software, related simulation analysis and modifying the control parameters of the controller. It is conducted stand test according to the test scheme for the clutch automatic control system. And the test data is record and made an analysis on. The control algorithm is verified by stand test, greatly improving the bonding quality of the clutch.

Boiler Drum

The three-pulse system of automatic control of the water level in the boiler drum received maximum distribution in the energy sector, as well as its modifications, which have the following disadvantages : the presence of static control errors at the end of the transition process in the development of internal disturbances and disturbances of superheated steam flow; large level deviations with sharp and significant changes in the load, which often leads to unloading or shutdown of the boiler or power unit. To eliminate these drawbacks, invariant systems for automatic regulation of the power supply of the drum boiler were previously developed. In work the system of automatic control of technological parameters of water level in a drum of steam boilers is considered. The description of control systems and a detailed description of the electrical power systems of the control system are given. Various methods of tuning the PI controller of a typical three-pulse automatic power control system are considered. The application of the method of structural-parametric optimization and the theory of invariance makes it possible by changing the structure of the system and optimizing the dynamic adjustment of the automatic power control system to significantly improve the quality of maintaining the water level in the boiler drum. Invariant automatic control systems eliminate static control errors under all influences and can significantly improve the quality of maintaining the level under variable conditions. The methods are proposed to significantly improve the quality of water level control in the boiler drum, eliminating the shortcomings of the typical automatic control system. The results of the work can be used in the design of power control systems of steam drum boilers. The results obtained can be used in the development of adaptive control systems for other thermal power facilities.

Quality Of Control

Not a few devices of food production work periodically and programmers are widely used to control these devices. Using logical devices that transfer between program sections can significantly improve the quality of control, but these methods are not sufficiently studied.The research is devoted to the development of a programmer for the implementation of programs with nonlinear time areas, containing logical devices in its structure. Single-loop and combined programmable automatic control system (ACS) with logical devices and without them were investigated and a comparative analysis of their work was performed.

Abstract. Combined with the Jiangbei wastewater treatment plant project in Yushu city, Jilin province, China, the design scheme, the system and the function for the automatic control system were summarized. The problems of the great change of water quality and quantity, dissatisfaction of design load and other issues existed in WWTP were solved. From the aspects of control strategy and microbial reaction mechanism, etc., the energy consumption for each processing unit under the control of automatic control system was analyzed. And the system performance and power consumption were evaluated by the WWWP’s operation results. The results show that: the quality of effluent is stable and the energy saving effect is remarkable by the use of automatic control system.
