Sistem kendali dapat dikatakan sebagai hubungan antara komponen yang membentuk sebuah konfigurasi sistem, yang akan menghasilkan tanggapan sistem yang diharapkan. Jadi harus ada yang dikendalikan, yang merupakan suatu sistem fisis, yang biasa disebut dengan kendalian (plant). Masukan dan keluaran merupakan variabel atau besaran fisis. Keluaran merupakan hal yang dihasilkan oleh kendalian,...
Ideal versus standard PID form   The form of the PID controller most often encountered in industry, and the one most relevant to tuning algorithms is the standard form. In this form the gain is applied to the , and terms, yielding: where is the integral time is the derivative time In this standard form, the parameters have a clear physical meaning. In particular, the inner...
The derivative of the process error is calculated by determining the slope of the error over time and multiplying this rate of change by the derivative gain Kd. The magnitude of the contribution of the derivative term to the overall control action is termed the derivative gain, Kd. The derivative term is given by: Derivative action predicts system behavior and thus improves settling time...
