Abstract

The invention relates to the technical field of automatic control, in particular to a clearance elimination control system and a full-clearance-elimination control method. The clearance elimination control system comprises a feeding device, two transmission devices, a power output device and a load which are mutually connected, and state information of the load is fed back to the feeding device. The full-clearance-elimination control method comprises the steps that the load state feedback information is received, a deviation value is obtained, and a current demand value of a first driving unitand a current demand value of a second driving unit are obtained; a first motor is driven to operate through the current demand value of the first driving unit, a second motor is driven to operate through the current demand value of the second driving unit, and power is output to the load, and the state information of the load is fed back to the feeding device. The clearance elimination control system and the full-clearance-elimination control method at least have the following advantages that the control system is simple in structure and convenient to operate, a current is automatically distributed to the two transmission devices after signal feedback and data comparison, thus a nonlinear clearance is eliminated, the control accuracy is improved, and the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to an anti-backlash control system and a full anti-backlash control method. Background technique [0002] In the field of high-precision servo control, some applications use a transmission structure in which dual motors of the same power drive the load together. There are nonlinear gaps between the reduction box and gears in the transmission mechanism, and the nonlinear gap will affect the dynamic and steady-state performance of the system when the load is started or reversed. [0003] Aiming at the non-linear backlash problem caused by dual motor drives with the same power, researchers have carried out a lot of theoretical and application research. The existing closed-loop control methods for anti-backlash position can be mainly divided into constant torque compensation control, torque based on speed deviation, etc. Control, torque compensation control based on a given c...
