Abstract

A method is proposed to reduce the steady- and/or transient-state error that occurs in the conventional proportional P controller. The method is based on the observer theory and programmed in the microprocessor. The deadbeat observer can estimate the sum of all the external forces quickly with a very simple structure. The new torque regulator based on this observer is expected to realize no steady-state-error and little transient-state-error position control even in using only the P controller, whether various types of external force are imposed or not. Moreover, according to the observer theory, this system has merit, in that this response to the external force can be determined independently of the response to the position reference. Numerical and experimental results are also shown. 9 refs.
