Application of Fuzzy Logic Algorithms in Load Control System of Electric Drive of Coal Combine

A new algorithm for adjusting PI controller coefficients in shearer operation control

“…Modern research shows that the load on the cutting tool can be adjusted by changing the speed of movement of the shearer itself by using a variablefrequency electric drive in the shearer feeding system [3]. To accomplish this, a cutting current (load) controller (CCC) is installed in the shearer control system-CCC in the form of a PI controller designed to prevent the overloading or overturning of the cutting drive motor by controlling the operating current parameter of the cutting motor I c with a signal from the current sensor by changing the feed speed V f of the shearer when the coal cutting resistance A and the operating conditions of the shearer change.…”

“…For instance, according to [1], in the period between 2005 and 2018, the Vietnamese mining industry replenished the amount of the state treasury by 9.39% of GDP. To achieve gains, the mineral production needs advanced technologies, including high-performance machines and equipment [2][3][4][5][6][7][8], environmental mitigation [9][10][11][12], as well as process automation and digitalization [13,14]. One of the fields that demands much mineral resources is construction, and the main construction material is crushed granite.…”
