Abstract
A pumping apparatus for a jetted-fluid system includes a pump having an inlet connectable to the drain, and an outlet connectable to the return. The pump is adapted to receive the fluid from the drain and jet fluid through the return. The apparatus includes a motor coupled to the pump to operate the pump, a sensor configured to generate a signal having a relation to a parameter of the motor, and a switch coupled to the motor and configured to control at least a characteristic of the motor. The apparatus also includes a microcontroller coupled to the sensor and the switch. The microcontroller includes a model observer configured to receive a first value based on the signal and to generate a second value representative of at least one of a modeled flow or a modeled pressure based on the first value. The microcontroller is configured to control the motor based on the second value.
