Title: Positioning servo controller
Inventor: TOMITA KOJI
IPC: G05B11/36
Filed: 2000-05-15
Abstract: PROBLEM TO BE SOLVED: To provide a positioning servo controller, capable of obtaining a satisfactory control response even if the physical quantity of an object to be controlled is unknown. SOLUTION: An acceleration controller 8 outputs a value obtained by amplifying an acceleration deviation between an acceleration command generated by adding a value outputted from a feed forward controller 7 to a valued outputted from a speed controller 2 and the acceleration of a motor 4 by an acceleration loop gain Ka as a torque command. Thus, even if an inertia J of the motor 4 included in the coefficient of a transmission function with a position command θr as an input and a position response θ as an output is unknown, the acceleration loop gain Ka is defined as the denominator of the inertia J of the motor 4 in the transfer function. Thus, the value of the acceleration loop gain Ka is set, so as to be a proper value and influence due to the inertia J of the motor 4 on the position response θ becomes negligible.
