Introduction

Paul F. Fisher is a notable inventor based in West Des Moines, Iowa, with a focus on enhancing the efficiency and safety of turbomachinery operations. He holds three patents that reflect his innovative contributions to the field.

Latest Patents

Fisher's latest patents include an "Apparatus for the prevention of critical process variable excursions in one or more turbomachines." This invention addresses the need to limit or constrain various process variables in systems utilizing turbocompressors and turbines. By implementing a combination of closed loop and open loop limit control schemes, his invention effectively prevents excursions into unfavorable operational conditions. The transition between open loop and closed loop control is optimized by assessing the direction and magnitude of the rate at which the limit variable is changing. If the rate of change suggests that recovery is imminent, control is reverted back to the closed loop limit control function.
