Plastering works are distinguished by complex technology and the use of a large number of manual working methods. Eliminate manual labor, significantly increase productivity and improve the quality of the plastering is possible based on the automation of applying plaster. The article discusses two ways to control the amount of plaster mixture: direct regulation of the amount of plaster mixture by changing the performance of the nozzle and regulation of the amount of plaster mixture by optimizing the speed of the nozzle. The disadvantage of the first method is the need for preliminary calculation of the time instant of the nozzle productivity change. The difficulty in solving this problem is due to the inertia of the device. In connection with these difficulties, it is proposed to use the second method of adjusting the amount of plaster mixture by optimizing the speed of the nozzle. The simulation of the proposed control system was carried out in the Matlab Simulink. The developed technique for applying plaster during automatic adjustment of the nozzle speed provides the necessary speed of the working tool depending on the surface irregularities.
