【摘要】：根据液压变压器控马达系统工作原理和系统动态方程,利用线性化理论,建立并简化了系统传递函数.理论分析表明,液压变压器控马达系统同时具有最小相位系统和非最小相位系统的性质.对于等配流槽液压变压器,当液压变压器控制角小于30°时,系统为最小相位系统;当液压变压器控制角大于30°时,系统为非最小相位系统.仿真结果表明,当液压变压器控制角大于30°时,系统的阶跃响应表现为负响应,系统具备非最小相位系统的特性.通过实验研究,进一步证明了理论分析和仿真分析的结果.研究表明,液压变压器控马达系统不适用于高精度转矩转速控制系统.
[Abstract]:According to the working principle and system dynamic equation of hydraulic transformer control motor system, the system transfer function is established and simplified by using linearization theory. The theoretical analysis shows that. The hydraulic transformer control motor system has the properties of both the minimum phase system and the non-minimum phase system. For the hydraulic transformer with equal distribution slot, when the control angle of the hydraulic transformer is less than 30 掳, the system is the minimum phase system. When the control angle of the hydraulic transformer is greater than 30 掳, the system is a non-minimum phase system. The simulation results show that the step response of the system is negative when the control angle of the hydraulic transformer is greater than 30 掳. The system has the characteristics of non-minimum phase system. Through the experimental research, the results of theoretical analysis and simulation analysis are further proved. Hydraulic transformer motor control system is not suitable for high precision torque and speed control system.

【正文快照】： 液压变压器和恒压网络技术的产生和发展,在理论上实现了无节流损失的压力调节.液压变压器不仅可以驱动直线负载,同时也可以驱动旋转负载.阀控系统中,由于存在节流损失,系统工作效率较低,泵控系统的出现则明显减少了能量损失,提高了系统效率[1],液压变压器控系统则集中了泵控系
