Based on minimum integral of time-multiplied absolute error and the optimal poles matching of the filter transform function, two optimal filters are recommended for construction of the robust process control system and essential robust for the system is deeply shown on modern engineering control theory. 根据时间乘绝对误差的积分值最小及滤波器传递函数的最优极点配置,在此推荐两种应用于鲁棒过程控制系统的滤波器,同时按照现代工程控制理论,深刻揭示这类系统的本质鲁棒性。
A new performance criteria, generalized integral of time absolute error ( GITAE ), is proposed and used in the optimization of PID controller parameters. Better performance and larger gain margin can be achieved comparing to using ITAE. 本文提出一种新的误差积分准则,即广义误差绝对值乘时间积分(GITAE),它能获得比ITAE更优的响应曲线以及更大的幅值稳定裕度。
After analysis of open loop characteristics of Compounded Switch-mode Hydraulic Power Supply, thesis takes Integral of Time-weighted Absolute Error ( for short, ITAE ) as the rule for building optimum tracing controller. Through research, II mode of ITAE is chosen. 在分析开环系统的特性之后采用时间加权的误差绝对值积分(integraloftime-weightedabsoluteerror,简称ITAE)准则,得出П型系统最优跟踪控制器。
Then an optimized tuning of PID parameter was carried out using optimized method of many variables with no restriction based on the target of integral of time multiplied absolute error ( ITAE ). 在此基础上采用单纯形法对PID参数进行基于时间乘绝对误差积分(ITAE)指标的最优整定。
The integral of time multiplied absolute value of error ( ITAE ) is also provided as a comprehensive performance index. 同时还提供时间乘以误差绝对值积分(ITAE)作为综合性能指数。
