1. A hydraulic system, comprising:
a linear hydraulic actuator having first and second ports;
an integrated hydraulic pump assembly conjoined with the linear hydraulic actuator to provide hydraulic fluid to operate the linear hydraulic actuator, the integrated hydraulic pump assembly including,
a casing wall defining an interior volume, the casing wall having a third port to provide fluid communication between the interior volume and the first port, and a fourth port to provide fluid communication between the interior volume and the second port,
a fluid driver assembly disposed inside the interior volume, the fluid driver assembly having at least one fluid driver with each fluid driver having at least one of a variable-speed motor or a variable torque motor,
at least one sensor assembly disposed in at least one of the casing wall or the interior volume and having at least one of a pressure transducer, a temperature transducer, or a flow transducer,
a first valve assembly disposed in at least one of the casing wall or the interior volume and in fluid communication with the third port, and
a second valve assembly disposed in at least one of the casing wall or the interior volume and in fluid communication with the fourth port; and
a controller that opens the first and second valve assemblies to provide fluid communication between the interior volume and the third and fourth ports, respectively, and establishes at least one of a speed or a torque of the motor in each of the at least one fluid driver to exclusively adjust at least one of a flow or a pressure in the hydraulic system to an operational set point.
