The digital implementation of the controllers is mainly preferred from re-programmability point of view. Many important control problems can be effectively solved using a digital architecture in conjunction with analog-digital and digital-analog conversion. Digital solutions offer very attractive advantages as promise to shorten design cycles and provide the freedom to reprogram in simple ways. However, depending on the complexity of the plant digital implementation may be demanding due to the high computational power requirement to run in real time. The necessity for the acquisition of the...
