Engine Operation Simulation Control System Design And Research

This paper presents a simulation test control system of an airplane engine operating system, which control motor to simulate the force and velocity of throttle lever and the torque on axis. The paper first describes the design of system, then sets up the model of simulation. In order to meet the requirement of system, the high-precision sensors, the PWM power magnifier and high-performance torque motor were used in the system. The watchdog circuits ensure the system run safely. The variable structure PID control and switching between torque control and position control were used to improve the performance of system during the simulation, which had good effects in the experimentation. As for the problems in the experimentation, such as the slow response speed of axes torque control, the disturbance of torque control to position control of throttle lever and the torque fluctuation of axis, solutions had been put forward and proved theoretically.
