ABSTRACT:
A control system for moving a piston in a reciprocating piston respirator which utilizes predictive servo control techniques. Present invention uses nonlinear time domain analysis rather than linear frequency domain analysis to produce a predictive servo control system for precisely controlling the movement of a piston in a reciprocating piston respirator. A plurality of flow profiles can be produced using stored factor tables. Current pressure and position information are used in the predictive servo control system.
