# Control for hydraulically operated construction machine having multiple tandem articulated members

## Abstract

An apparatus and method for controlling a hydraulically operated construction machine, having a plurality of tandem articulated members which are controlled in a manner that movement of one of the members is controlled in response to movement of another of the members, in order to move the members in a predetermined pattern. The members are controlled in response to the anticipated future movement of the another member. Anticipated future movement of the another member may be determined, for example, as a function of the present position and velocity of the another member and system delay in movement of the another member. Where the another member is controlled manually by an operator control lever coupled with a manual hydraulic control valve, anticipated future movement may be determined by monitoring actuation of the control lever.
