STUDY OF AUTOMATIC CONTROL SYSTEMS FOR HELICOPTERS PART 3: ANALYTICAL STUDY OF RPM CONTROL FOR THE SINGLE SPOOL TURBOPROP ENGINE

Abstract

Control systems were investigated in which the engine regulators and the attitude stabilizer blend well together. The engine initially studied was of the 280-hp Artouste turboprop type. Three simple configurations were analyzed by means of root locus procedures: (1) intergral control in the rpm feedback loop and proportional control in the temperature feedback loop; (2) proportional control in the rpm feedback loop and integral control in the temperature feedback loop; and (3) integral control in the rpm feedback loop and rate control in the temperature feedback loop. No specific grain values were recommended, but the third configuration seemed likely to give the best dynamic response. Figures showing the main pole-zero points for all 3 loops in each configuration are presented.
