PID Full Form In Engineering English
In engineering, PID stands for Proportional-Integral-Derivative. It refers to a type of control system widely used in industrial automation and process control. A PID controller is an essential component in control engineering that continuously calculates an error value as the difference between a desired setpoint and a measured process variable. The controller applies correction using three control terms: proportional, integral, and derivative.
The Proportional term responds to the current error, the Integral term considers the accumulation of past errors, and the Derivative term predicts future errors based on the current rate of change. Together, these three elements ensure precise and stable control over systems such as temperature regulation, motor speed, fluid flow, and pressure control. Due to its simplicity and effectiveness, the PID controller remains one of the most commonly used control algorithms in various fields of engineering, including electrical, mechanical, chemical, and aerospace systems.
PID Full Form In Engineering Hindi
इंजीनियरिंग में PID का फुल फॉर्म Proportional-Integral-Derivative होता है। यह एक नियंत्रण प्रणाली (Control System) है, जो विभिन्न औद्योगिक प्रक्रियाओं और स्वचालन (Automation) में उपयोग की जाती है। PID कंट्रोलर किसी प्रक्रिया के वांछित मान (Setpoint) और वास्तविक मान (Process Variable) के बीच के अंतर (Error) को मापकर उसे कम करने का कार्य करता है।
इसमें तीन मुख्य भाग होते हैं: Proportional (अनुपाती), जो वर्तमान त्रुटि पर कार्य करता है; Integral (समाकल), जो पिछले समय की त्रुटियों का जोड़ लेता है; और Derivative (अवकलज), जो त्रुटि के परिवर्तन की गति को देखता है। ये तीनों घटक मिलकर सिस्टम को स्थिर, सटीक और प्रभावी बनाते हैं। PID कंट्रोलर का उपयोग तापमान नियंत्रण, मोटर स्पीड, दाब नियंत्रण और फ्लो मैनेजमेंट जैसी कई इंजीनियरिंग प्रणालियों में किया जाता है। इसकी सरलता और प्रभावशीलता के कारण यह अत्यधिक लोकप्रिय है।
