Analysis Based on Transfer Function

Introduction

Nowadays the microcontrollers are more powerful and their prices are affordable which makes their use attractive. In mechatronic systems they are used either for On/Off or continuous-time controls. In both cases, the microcontroller is the hearth of the mechatronic system. In the On/Off case, it is used for security and control purposes. The algorithm in this case is easy and doesn’t take time in general to compute the action to be taken. While for the continuous-time case, the microcontroller receives the data at each sampling period and compute the desired action according to a chosen algorithm. The computation in this case may take more time and more care should be taken to prevent surprises. In both cases interrupts are used. The microcontrollers we will use in this book must have a quite high processing speed.
