Kontrola da Maimakon PID da Sabon PID a Cikin Sistemai na Kontrola

Na'ura da PID tana nufin na'ura da proportional–integral–derivative. Na'ura da PID wani na'ura ce ta yi amfani da shi a cikin sistem na'ura. Wannan irin na'ura tana da sunan na'ura da uku, kuma ana yi amfani da shi a kan PID Controller. Daga bincike da kula da hukumomin farko, integral da derivative ya danganta da ita, muna iya samun na'urori daban-daban don abubuwa masu yawan muhimmanci.

PID controllers suna neman da su ke da muhimmanci a cikin kwamfuta da suke suka faruwa. Nicholas Minorsky ya fara rubutu mai bayanin na'ura da PID controller. Don na'ura da PID, alama ta yi amfani da proportional error signal da derivative da integral of the error signal. Saboda haka, alama ta yi amfani da PID control shine:

Laplace transform da ya amfani da shi a kan alama ta yi amfani da PID control shine

Akawar na'urori za su iya samun su ne da amfani da biyu na uku daga parametoli da suke suka faruwa a kan PID controller. Biyu na uku suna iya yi aiki idan wadanda suka zama zero. Saboda haka, PID controller yana iya zama PI (proportion-integral), PD (proportional-derivative) ko kuma P ko I. Termi da ya zama D tana da muhimmanci a cikin bincike da kuɗi, sannan termi da ya zama integral tana da muhimmanci a cikin samun balon da suke suka faruwa. A lokacin gaba, PID controller tana yi amfani da shi a cikin wuraren mekaniki. Wadannan suna yi amfani da shi a cikin wurare-pneumatic saboda suke suka zama compressed air. Wurare-mekaniki sun hada da spring, lever ko mass. Yawanci, wurare elektronika masu yawan murabba'a suna da PID control loop. A lokacin yanzu, PID controllers suna yi amfani da shi a cikin PLC (programmable logic controllers) a cikin kasuwanci. Parametolin proportional, derivative da integral suna nufin Kp, Kd da Ki. Dukkan waɗannan uku parametoli suna taimakawa a cikin closed loop control system. Suna taimakawa a cikin rise time, settling time, overshoot da kuma steady state error

Na'ura da PID tana haɗa da muhimmanci daga proportional, derivative da integral. Ba ni a fada ba game da wannan na'urori.

Proportional Control: A nan, alama ta yi amfani da proportional error signal. Error signal tana da muhimmanci a cikin farkon reference input signal da feedback signal.

Derivative Control: A nan, alama ta yi amfani da proportional error signal da derivative of the error signal. Saboda haka, alama ta yi amfani da derivative control action shine:

Integral Control: A nan, alama ta yi amfani da proportional error signal da integral of the error signal. Saboda haka, alama ta yi amfani da integral control action shine:

A PID controller tana da batuwa, musamman a cikin optimal control. Babban batuwa shine feedback path. PID babu model da suke suka faruwa. Batuwan da suke suka faruwa sun hada da linear system da sensitivity da noise a cikin derivative part. Yanayi da kuɗi na iya saɗa output.
