1. A controller for controlling operating parameters associated with fluid flow, speed or pressure of a centrifugal pump for pumping fluid, wherein at least one sensor is coupled to said pump for generating a signal indicative of a sensed operating condition, said controller comprising:

  • a storage device for storing data indicative of an at least one operating condition; and

    a processor in communication with said sensor, the processor utilizing said at least one sensor signal and said stored data indicative of said at least one operating condition to generate a control signal which is applied to said pump, for correcting the speed thereof in order to maintain a requisite pump flow or pressure, said control signal including a stability factor that prevents overcorrection of said pump speed.
