摘要
介绍了在大迟延系统中,利用Sm ith(史密斯)预估器模型的补偿特性,并将其加入到被控系统的反馈回路来补偿过程的动态特性,以克服控制系统在纯PID控制、微分先行控制及中间反馈控制受定值扰动下所存在的超调量较大且响应速度很慢的缺点。
By utilizing the compensation characteristic of Smith predictor model, the dynamic characteristic of process was compensated by applying Smith predictor in the feedback loop of controlled system in large time-delay system, so it overcome the disadvantage of large overshooting and lower speed of response disturbed by the settled value when the control system is in unmixed PID control, differential advanced control, the intermediate feedback control.
