基于阶跃响应法的管制员工作启动安全绩效研究

Research on safety performance of controllers in start-up phase based on step response method

为分析管制员工作启动阶段的安全绩效特征,建立管制员工作阶跃响应模型;根据阶跃响应类型,确定不同阻尼比下的时域性能指标,然后采集20名管制员连续20 min划消试验的数据,通过Matlab软件计算管制员启动过程中的阻尼比及其时域性能指标。研究表明：根据阻尼比可将管制员启动类型分为振荡惯性启动（0〈ζ〈1）与单调惯性启动（ζ〉1）,管制员响应时间与其启动速率成反比。基于阶跃响应曲线的参数可用来有效鉴定管制员启动类型与启动速率等绩效特征。

To analyze the characteristics of safety performance of controllers in the start-up phase,a step response model was built for job performance. The time-domain performance indicators under different damping ratio were determined based on the step response types. 20 min continuous cancellation test data on 20 controllers were collected,and the damping ratio and its time-domain performance indicators were calculated in Matlab. The results indicate that the start-up types of controllers can be divided into oscillation inertia start-up（0〈ζ 〈1） and monotonic inertia start-up（ζ〉 1） based on the damping ratio,and the start-up speed is inversely proportional to the response time,and that the parameters of the step response curve can be used to identify the start-up type and the start-up speed of controllers effectively.
