Research On Design And Experiment Analysis Of The Electrical Passive Torque Servo Control System

The electrical torque load simulator is the key equipments in hardware-in-the-loop simulation of the weapon system. It is used to give real-time torque load to the rudder of aerocraft i.e missiles and planes. It's a typical kind of passive torque servo system. And the extrusive problem in this kind of system is the surplus torque, so it is very important that how to effectively design the system according to the characteristic of the system. Based on the design of servo control system of ET107B electrical torque load simulator, following jobs are finished in this paper.Firstly, the structure and working principle of the system is analysed in this paper, and the mathematical model of the load simulator with electrical rudder section and torque simulator section included is established,. The control method is researched by predigesting the model. The model of the system with uncertaintyes is verifyied by experiment.Secondly, the IP-IMC control method is proposed based on the analysis of the model and the design of the passive torque servo system is completed by combining the forwardfeed compensation, which is the hybrid control method.For the resonance in torsional, a control method implemented by improving the damp is proposed and its effectiveness is verified by simulations.Lastly, the designed controller is applied to ET107B simulator and the test experiments are analysed.All of the work shows that, the designed controller is effective in restraining surplus torque and resonance in torsional.
