An Investigation of RPV Control Criteria via the Optimal Regulator Performance Index.
Abstract
Remotely Piloted Vehicles (RPV's) have control requirements which differ, sometimes significantly, from the requirements for manned aircraft due to the fact that the pilot is not in the aircraft. This thesis discusses various manned-aircraft handling qualities specifications such as MIL-F-8785B and the C criterion and examines their applicablility to the RPV control problem. The desired performance is analyzed from the points of view of mission requirements and the needs of the operator to control the vehicle. The linear optimal regulator is then proposed as a means to minimize state errors and control magnitudes in the closed-loop response. A quadratic performance index is used to investigate the effect on controller design of varying the relative importance placed on the various parameter errors. The longitudinal mode of a typical existing RPV is used for the analysis and the resulting relationships between the performance index weighting factors and the resulting controller configurations are presented. RPV flying qualities specifications and control console design are discussed and related to these relationships.
