Abstract:
A method for controlling movement of a pair of actuators by selectively moving a control member of a joystick controller, the method comprising:causing a tracking relationship between the control member and the first actuator in response to selective positioning of the control member within a first portion of a travel pattern defined by the joystick controller; causing a tracking relationship between the control member and a second actuator in response to selective positioning of the control member within a second portion of a travel pattern defined by the joystick controller; moving the first and second actuators proportionally in response to selective movement of the control member along at least one path which divides the first and second portions of the travel pattern; causing no more than an insubstantial movement of the first and second actuators in response to selective positioning of the control member along at least one path which divides one of the first or second portions of the travel pattern; generating first and second control signals in response to the selective positioning of the control member along at least one path which divides one of the first or second portions of the travel pattern; and delivering the first and second control signals to opposing portions of a control valve.
