发动机部件工控组态软件运行温度补偿仿真

Simulation of Operation Temperature Compensation of Industrial Control Configuration Software for Engine Parts

对发动机部件工控组态软件温度的补偿,能够有效控制发动机的稳定运行。对工控软件进行温度补偿,需要对软件温度拐点进行计算,对温度补偿决策机制进行确定,完成工控组态软件运行温度的补偿。传统方法对运行温度采样数据进行滤波,计算曲线的拐点,但忽略了对温度补偿决策机制的确定,导致其实现效果不理想。提出基于低通数字滤波的发动机部件工控组态软件温度补偿方法,通过分析发动机部件工控组态软件的动态特征,确定软件的谐振频率,并对软件运行温度有最大影响的弹性系数进行计算,实现工控组态软件运行的动态特征分析,对温度补偿数字滤波器进行设计,对发动机部件工控组态软件运行温度的拐点进行计算,确定软件运行温度补偿决策机制,提高温度补偿的效果。实验结果表明,所提方法温度补偿的效果较好,且补偿的及时性较高,温度补偿后软件的运行状态稳定。

This paper presents a temperature compensation method for industrial control configuration software of engine component based on low-pass digital filter. Through the analysis on dynamic characteristic of engine compo- nent of industrial control configuration software, our research determined the resonant frequency of software and calcu- lated the elastic coefficient which has large influence on software running temperature, so as to realize the analysis of dynamic characteristic of industrial control configuration software. In addition, this research designed digital filter of temperature compensation and calculated the inflection point of running temperature in industrial control configuration software of engine component. Finally, we determined the software running temperature compensation decision mech- anism to improve the effect of temperature compensation. Simulation results show that the proposed method has good effect of temperature compensation and high timeliness of compensation. Meanwhile, the running state of software is stable after temperature compensation.
