摘要
为实现电驱动机动平台发动机齿杆位置的电动控制,设计以TI公司DSP2808为核心的步进电机控制系统,它通过控制步进电机驱动脉冲数实现对平台发动机油门开度的控制,并针对发动机转速闭环控制时步进电机振荡和发动机非线性等因素引起的发动机转速不稳定问题,提出了发动机转速模糊PI控制。实验表明步进电机脉冲响应快,发动机转速动态响应良好,发电机输出电压平稳,为电驱动机动平台提供可靠电能,满足了电驱动平台对发动机控制的要求。
The stepper motor control system is designed with DSP 2808 of TI company as its core for fulfilling the electric control of engine fuel pump rack in electric-drive mobile platform. The system achieves the engine fuel rack control by controlling the driving-pulse number of stepper motor, and a fuzzy PI control for engine speed is proposed to tackle the problem of engine speed instability caused by stepper motor fluctuation and engine nonlinearity during engine speed closed-loop control. Experimental results show that the pulses of stepper motor respond swiftly, engine speed has a good dynamic response and the output voltage of generator is stable. These provide reliable electric energy for mobile platform, meeting its requirements on engine control.
