Control System Engineering
The control system is that means by which any quantity of interest in a machine, mechanism, or other equipment is maintained or altered in accordance with a desired manner.
SKU- Control Engineering is an online training course designed for the students. Different topics are explained with flash animations and suitable illustrative examples. Interactive simulations are provided for clear understanding of the concepts.
The course prepares very carefully a background of each topic with essential illustration and practical examples and then step by step gives the complex derivation and explanation.
