The course explains the basic building blocks of the electric drive. The designof components, electrical drives, typical load characteristics. Further are discussed the basic control structures for drives with DC and AC motors and components required for their implementation as the structure of a control computer circuits to switch from analog signals to digital and implementation regulators themselves in digital form.
