Q. Working of Microprocessor Control?
The microprocessor, which has rapidly become a key component in digital control systems, and its associated circuits function as the digital processor. It is often used as a dedicated computer in which the chip itself is programmed to perform specific functions. Digital watches and auto fuel-injection systems are examples. With microprocessor control, not only the same hardware can be used to perform a variety of tasks by reprogramming, but also distributed computation (which results in less expensive and more reliable operation than centralized control) is possible with interconnection and intercommunication of several microprocessors.
Figure shows a block diagram of a microprocessor-controlled dc motor system, in which the controlled process consists of a dc motor, the load, and the power amplifier.
