A real-time path-directed controller is disclosed. The controller is extraordinarily well-suited for navigating a vehicle along a desired path across a field for agricultural applications. The controller comprises several important assemblies. It comprises a position sensor which produces an object position signal to an object position signal conditioning module (which, in turn, produces a conditioned object position signal to a controller summer). The controller also comprises a heading conditioning module for receiving the object position signal and conditioning the object position signal to produce a conditioned heading signal to the controller summer. The controller also comprises a control apparatus sensor for producing a control apparatus signal to a control apparatus signal conditioning module (which, in turn, produces a conditioned control apparatus signal to the controller summer). The controller also comprises a control apparatus null position conditioning module for conditioning a distance-differentiated object position signal and conditioned control apparatus signal to produce a conditioned null position signal to the controller summer. Finally, the controller comprises a controller summer summing the conditioned object position signal, the conditioned heading signal, the conditioned control apparatus signal, and the conditioned null position signal to produce a controller summer signal to a controller summer conditioning module so as to produce a control apparatus control signal to a control apparatus controller so as to direct the control apparatus and thereby direct the object by feedback control along the desired path.

Navigation control system

A real-time path-directed controller for navigating an object along a desired path is disclosed. The controller comprises: a position sensor which contributes to the production of a conditioned object position signal to a controller summer; a heading conditioning module which contributes to the production of a conditioned heading signal to the controller summer; a control apparatus sensor which contributes to the production of a conditioned control apparatus signal to the controller summer; and a control apparatus null position conditioning module which contributes to the production of a conditioned null position signal to the controller summer. The controller summer sums the signals to produce a controller summer signal to a controller summer conditioning module so as to produce a control apparatus control signal to a control apparatus controller so as to direct the control apparatus and thereby direct the object by feedback control along the desired path.
