摘要:提出了在PID条件下闭环辨识的方法,运用频域法,通过有关模和相角的关系,辨识出假定二阶过程模型的有关参数。仿真试验表明这种方法是可行的,而且基本满足大时滞的辨识精度。
A method of closed-loop identification under PID and identifying parameters of proposed second-order process model through relationship of mode and phase in frequency domain method are proposed.Simulation has shown this method is feasible and good accuracy for identification of large dead-time process.
