A fairly successful exploration of multi-objective optimization of aircraft flight control system design using time-domain Neal-Smith criterion

Sections 1 and 2 of the full paper explain what we believe to be a fairly successful exploration. Their core consists of; (1) to match the pilot and the aircraft, with the man-vehicle closed loop reference model, we introduce the flight quality requirements into the optimization algorithm to design the aircraft flight control system; (2) we establish the equivalent model of the aircraft with the CAP criterion; (3) using the time-domain Neal-Smith criterion, we perform the multi-objective optimization to obtain the optimal pilot reference models under different tasks; (4) we select the optimal pilot reference model according to the flight quality requirements and combine it with the aircraft equivalent model to form the man-vehicle closed loop reference model; (5) with the man-vehicle closed loop reference model, we design the aircraft flight control system by using the multi-objective optimization algorithm. Section 3 simulates the multi-objective optimization of the pilot reference model and the man-vehicle closed loop reference model; the simulation results, given in Figs. 5 through 8, and their analysis show preliminarily that our multi-objective optimization algorithm can not only tune the parameters of the controller of the aircraft flight control system but also select the optimal pilot reference model under different tasks and use the optimization results to evaluate the PIO (pilot-induced oscillation) susceptibility.
