FIELD: automatic control. SUBSTANCE: proportional-differential controller has meter of controlled parameter kinematically coupled to swing axle of summing lever which one end is linked to piston of dash-pot and spring connected to rod of piston of servomotor coupled to controlling element. Spaces above and beneath cylinder of servomotor are connected to pump through shut-off amplification control valve kinematically linked to the other end of summing lever. Dash-pot piston is provided with correcting inertial mass and air-tight space to ensure zero buoyancy of this piston in working fluid surrounding it. EFFECT: improved automatic control characteristics. 1 dwg
