Based on an introduction to the structure and principle of electrical loading system, a mathematical model of the system was put forward to analyze and to simulate its stability and anti-jamming. By including multi-feedback and feedforward in the system and using control methods to control DC-motor, improved performance of the system was obtained. Simulation results indicated that the performance of the motor-drive load simulator is as good as that of the electro-hydraulic load simulator in the range of small torque.
