In the hardware-in-the-loop simulation, the goal of electric loading is to realize the accurate tracking of the torque signal and test the performance of the aircraft actuator system. For some high dynamic aircraft, it is necessary to reduce the influence of the surplus torque to increase the system frequency band. This paper introduces a new electric loading system which adopts a double-loop servo motor as the torque loading mechanism. It applies two loops to track the position of the rudder and the aerodynamic load spectrum respectively. For the purpose of reducing the disturbance between two loops of the scheme, a two-DOF H∞ robust controller is designed, which improves the robustness of the system effectively. The simulation results show that the new system increases the upper limit of 25 Hz frequency band of the traditional single-loop system with PID control to the maximum of 40 Hz. The double-loop system thereby meets the technical requirements of the hardware-in-the-loop simulation experiment for high dynamic aircrafts.

“…If one wishes the control of the load machine to be totally independent of the test machine (which means that the load machine is essentially a self contained load emulator), then high bandwidth measurements of the shaft torque are required. Furthermore, the control usually involves the use of derivatives, and therefore can be compromised if there is noise on the measurements [3], [7], [9]. An alternative approach, which does not require the use of derivatives and does note require a torque transducer, is based on controlling the torques of both of the machines so that the correct emulation is obtained [1], [2], [4].…”

“…The load emulation can be used for the controller design and validation, the testing of electrical machines and variable speed drives under the complex load conditions, in the laboratory environment (1)(2)(3)(4). Such a laboratory based emulation facility is often required when a load application is situated on a remote site or in a hazardous environment.…”

This paper proposes a neuro-fuzzy controller for a vector controlled load machine (dynamometer) which is mechanically coupled to a drive machine for the emulation of nonlinear loads. The main objective is to provide a system for testing of high performance electrical drives under nonlinear loads. The proposed emulation strategy is based on the model reference control approach using an on-line trained Neuro-Fuzzy Controller (NFC). The emulation is placed in the closed speed loop of the drive machine. Varieties of dynamic load models which are the nonlinear functions of the shaft speed are successfully emulated and the generalization capability of the trained NFC is shown. Simulation results showing the excellent performance of the proposed emulation strategy are presented.Keywords: Neuro-fuzzy controller, mechanical load emulation, permanent magnet synchronous motor (PMSM).
