A gas supply and pressure control system delivers controlled pressurized gas according to an electrical command. The system includes a gas supply sub-system outputting a continuous high-pressure gas supply. A pressure control sub-system is provided in fluid communication with the gas supply sub-system and receives the continuous high-pressure gas supply. The pressure control sub-system provides a modulated pressure to a downstream volume, such as actuators for active seals in a turbomachinery environment, based on the electrical command.
