PID-based Practical Digital Control with Raspberry Pi and Arduino Uno

En savoir plus sur le livre

The Arduino Uno is an open-source microcontroller development system that includes hardware, an Integrated Development Environment (IDE), and extensive libraries, supported by a large community of programmers, engineers, and enthusiasts. These libraries simplify programming and testing, as they are often pre-tested and functional. The Raspberry Pi 4 is versatile, applicable in audio/video devices, industrial controllers, robotics, gaming, and various domestic and commercial uses. Its Wi-Fi and Bluetooth capabilities enhance its suitability for remote and Internet-based control and monitoring applications. This book focuses on utilizing both the Raspberry Pi 4 and Arduino Uno in PID-based automatic control applications. It begins with the fundamentals of control systems and feedback control, providing tested projects for real-life PID controller implementations. Topics include open-loop step time response, PID parameter tuning, and closed-loop time response, accompanied by block diagrams, circuit diagrams, PID controller algorithms, and complete program listings for both platforms. The projects aim to teach PID theory and applications, allowing for modifications for other uses. Projects designed for the Raspberry Pi 4 are compatible with other models in the Raspberry Pi family. The book covers various essential aspects of these technologies.
