Q. Sampled-data and digital control systems?
These differ fromthe continuous-data systems in that the signals at one or more points of the system are in the form of either a pulse train or a digital code. Sampled-data systems usually refer to a more general class of systems whose signals are in the form of pulse data, whereas a digital control system refers to the use of a digital computer or controller in the system. The term discrete-data control system is used to describe both types of systems.
A three-phase, 400-V, wye-connected induction motor takes the full-load current at 45 V with the rotor blocked. The full-load slip is 4%. Calculate the tappings k on a three-phase
