【Abstract】 According to the technical desires, a scheme of designing and researching on the limited angle brushless torque motor (LABLTM) used for the electronic governor’s actuator of diesel engine is advanced. In this paper, the structure, principle and design characteristic of LABLTM prototype, is introduced. The main work is to construct the mathematics model of LABLTM prototype, research the controlling strategy, design the driving module of LABLTM prototype and research on the experiments.The research focus on the following implementation.With the electromagnetism principle and the machine movement rule, according to the idiographic configuration and movement equation of the LABLTM prototype, this paper does the logical predigestion, analyzes and calculates movement characteristic of LABLTM prototype, establishes the mathematics model. Based on that, this paper built up the simulation model of the controlling system.Though the optimizing and researching on the controlling strategy, the paper uses the four-closed loop controller scheme that made up of the loop of position, the loop of angle’s acceleration, the loop of angle’s speed and the loop of current as the optimal strategy in this paper.Based on researching on the controlling strategy and integrating the merit and disadvantage between the digital circuit and the analog circuit, this paper uses the analog circuit to design the controlling module ,which uses the four-closed loop controller as its core, it mainly makes up of the given inputting circuit of angle’s position, the sensor invalidation protecting circuit, the position detecting circuit, the four-closed loop controller circuit, the logical H-bridge circuit of power driving, the triangle wave producing circuit, the PWM producing circuit, the current detecting circuit and others assistant circuits that the controlling system needs.The prototype of the LABLTM and the driving module were tested on steady and dynamic performance and electronic governor’s experiments. The result shows that the prototype LABLTM and the driving module were satisfied of the designing demand, with good performance and meeting of the simulating result. It satisfied for the demand of the electronic governor’s actuator of diesel engine.更多还原
