ACCELERATION/DECELERATION TIME CONSTANT CONTROL SYSTEM OF ROBOT.

摘要

An acceleration/deceleration time constant control system of a robot for controlling the operations of the robot while setting the acceleration/deceleration time constant of a servomotor to an optimal value for each block. An arrival speed is determined from a travelling amount of a block (S1-S4). An output torque (Tmax) of the servomotor is determined from this arrival speed (S5), and a static load torque (Twn) is substracted from this output torque (Tmax) to obtain an acceleration torque (Tan) (S6). An acceleration (an) is obtained from this acceleration torque (Tan) and a load inertia of the servomotor (S7), and an acceleration/deceleration time constant ( tau ) is determined from this acceleration (an) (S8). With this operation, an optimal acceleration/deceleration time constant can be determined.
