An electrohydraulic positioning control system (200, 400) comprising: a shuttle valve (240, 440) configured to direct fluid flow between a selectable one of a first fluid port and a second fluid port, and a fluid outlet configured to be fluidically connected to a fluid actuator; a first servo valve (220a, 420a) controllable to selectably permit flow between the first fluid port and a fluid source (202, 402), permit flow between the first fluid port and a fluid drain (228a, 228b), and block fluid flow between the first fluid port, the fluid source (202, 402), and the fluid drain (228a, 228b); a second servo valve (220b, 420b) controllable to selectably permit flow between the second fluid port and the fluid source (202, 402), permit flow between the second fluid port and the fluid drain (228a, 228b), and block fluid flow between the second fluid port, the fluid source (202, 402), and the fluid drain (228a, 228b); a first servo controller (234a, 434a) configured to provide a first health signal and control the first servo valve (220a, 420a) based on a position demand signal, a position feedback signal (412a, 412b), a first priority signal, and a second health signal; and a second servo controller (234b, 434b) configured to provide the second health signal and control the second servo valve (220b, 420b) based on the position demand signal, the position feedback signal (412a, 412b), a second priority signal, and the first health signal wherein either the first priority signal or the second priority signal comprises a representation of an operational condition comprising a high priority command provided to a selected one of the first servo controller (234a, 434a) or the second servo controller (234b, 434b) to act as a primary servo controller. a shuttle valve (240, 440) configured to direct fluid flow between a selectable one of a first fluid port and a second fluid port, and a fluid outlet configured to be fluidically connected to a fluid actuator; a first servo valve (220a, 420a) controllable to selectably permit flow between the first fluid port and a fluid source (202, 402), permit flow between the first fluid port and a fluid drain (228a, 228b), and block fluid flow between the first fluid port, the fluid source (202, 402), and the fluid drain (228a, 228b); a second servo valve (220b, 420b) controllable to selectably permit flow between the second fluid port and the fluid source (202, 402), permit flow between the second fluid port and the fluid drain (228a, 228b), and block fluid flow between the second fluid port, the fluid source (202, 402), and the fluid drain (228a, 228b); a first servo controller (234a, 434a) configured to provide a first health signal and control the first servo valve (220a, 420a) based on a position demand signal, a position feedback signal (412a, 412b), a first priority signal, and a second health signal; and a second servo controller (234b, 434b) configured to provide the second health signal and control the second servo valve (220b, 420b) based on the position demand signal, the position feedback signal (412a, 412b), a second priority signal, and the first health signal wherein either the first priority signal or the second priority signal comprises a representation of an operational condition comprising a high priority command provided to a selected one of the first servo controller (234a, 434a) or the second servo controller (234b, 434b) to act as a primary servo controller.
