AUTOMATIC CONTROL METHOD FOR SYSTEM WITH CONTROL LINKAGE BACKLASH AND DEVICE WHICH IMPLEMENTS SAID METHOD Russian patent published in 1998 - IPC

FIELD: automatic control systems. SUBSTANCE: method involves addition of error signal with pulse correction signal which in case of control linkage backlash is generated by subtraction of current value of control linkage backlash from signal which is equal to its half range and which sign is equal to error signal sign. Corresponding device which implements said method has mismatch detector for preset signal and main feedback signal, regulator, adders, electric motor with angle detector, non-linear circuit of control linkage backlash type and controlled object with angle detector, non-linear correction circuit of saturation type. EFFECT: increased precision of control linkage backlash compensation, improved dynamic characteristics. 2 cl, 5 dwg
