A hydraulic system comprising: a hydraulic pump to provide hydraulic fluid to a hydraulic actuator having first and second ports (22,24), the hydraulic pump including, at least one motor, the at least one motor being at least one of a variable-speed and a variable-torque motor, and a gear assembly to be driven by the at least one motor such that fluid is transferred from an inlet port of the hydraulic pump to an outlet port of the hydraulic pump; a first control valve assembly including, a first control valve disposed on a side of the inlet port, the first valve in fluid communication with the first port and the inlet port, and a first control valve actuator to operate the first control valve; a second control valve assembly including, a second control valve disposed on a side of the outlet port, the second valve in fluid communication with the second port and the outlet port, and a second control valve actuator to operate the second control valve; and a controller, wherein the controller concurrently establishes at least one of a speed and a torque of the at least one motor and an opening of the first and second control valves (2114,2014) so as to maintain at least one of a flow and a pressure in the hydraulic system at an operational set point. a hydraulic pump to provide hydraulic fluid to a hydraulic actuator having first and second ports (22,24), the hydraulic pump including, at least one motor, the at least one motor being at least one of a variable-speed and a variable-torque motor, and a gear assembly to be driven by the at least one motor such that fluid is transferred from an inlet port of the hydraulic pump to an outlet port of the hydraulic pump; at least one motor, the at least one motor being at least one of a variable-speed and a variable-torque motor, and a gear assembly to be driven by the at least one motor such that fluid is transferred from an inlet port of the hydraulic pump to an outlet port of the hydraulic pump; a first control valve assembly including, a first control valve disposed on a side of the inlet port, the first valve in fluid communication with the first port and the inlet port, and a first control valve actuator to operate the first control valve; a first control valve disposed on a side of the inlet port, the first valve in fluid communication with the first port and the inlet port, and a first control valve actuator to operate the first control valve; a second control valve assembly including, a second control valve disposed on a side of the outlet port, the second valve in fluid communication with the second port and the outlet port, and a second control valve actuator to operate the second control valve; and a second control valve disposed on a side of the outlet port, the second valve in fluid communication with the second port and the outlet port, and a second control valve actuator to operate the second control valve; and a controller, wherein the controller concurrently establishes at least one of a speed and a torque of the at least one motor and an opening of the first and second control valves (2114,2014) so as to maintain at least one of a flow and a pressure in the hydraulic system at an operational set point.
