Proportional Integral

In this work, the problem of improving the quality of controlling the diesel engine crankshaft speed is considered. The principles that govern the control of this parameter in internal combustion engines are described. The advantages of the proportional-integral-differential (PID) control principle are shown. Calculations of the influence of the PID controller structure on the dynamic characteristics of the diesel engine rotational speed automatic control system are performed. The transient processes of acceleration–inhibition and load-dropping are investigated using a KamAZ-740 engine of a 100 kW diesel generator. Transient processes are achieved for different values of the proportional, integral and differential components of the PID control law. The influence of these coefficients on the quality indicators of the regulatory process such as the duration of the transient process and overshoot is evaluated.

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.
