Problems solved by technology

However, the increase of damping will seriously reduce the response bandwidth of the system. In the human sensory system, the system is viscous, the manipulation is inflexible, and it is impossible to produce a finer sense of force.

Description

technical field [0001] The invention relates to the field of control, in particular to a device and method for controlling torque. Background technique [0002] In all areas of torque control, there are certain requirements for fluctuations in the actual output of the motor. [0003] There are two main torque control methods commonly used at present: [0004] The first method is to directly control the current, indirectly control the output torque through the linear proportional relationship between the current and the torque, convert the target torque into the required current according to the torque coefficient of the motor and the mechanical transmission relationship, and directly send it to the driver to control the motor according to the given value. value output current. [0005] Method 2 Keep the above control structure unchanged, connect damping devices in parallel or in series at the output position to achieve the purpose of controlling the torque ripple range, an...
