为高燃速推进剂比冲测试提供了可靠的试验依据。
It is a reliable measuring method of the specific impulse for the high-burning rate propellants.
当启动频率较高时，启动时会造成失步，而停止时由于惯性作用又会发生过冲，所以在步进电机控制中必须要采取升降速控制措施。
When the startup speed is higher, stepping motor will lose steps. While stopping, it will also lose steps because of inertia. So, it needs to take speed control measures on control of stepping motor.
通过开车试验数据分析，折线法能够有效地解决冲速段的富油和冲速问题，实现冲速段的转速控制， 并且具备较强的鲁棒性。
Through analysis of engine ground test data, it's learnt that dogleg method can resolve efficiently the rich oil and overrunning problem, and achieve rotational speed control with strong robustness.
