Control
The control system is responsible for giving the required sequential pulses to the power circuitry in order to activate the phases as required. While it is possible to do this using electro-mechanical means such as commutators or simple analog or digital timing circuits, more control is possible with more advanced methods.
Many controllers in use incorporate programmable logic controllers (PLCs) rather than electromechanical components in their implementation. A microcontroller is also ideal for this kind of application since it enables a very precise control of the phase activation timings. It also gives the possibility of implementing a soft start function in software form, in order to reduce the amount of hardware required.

Famous quotes containing the word control:
“Religion differs from magic in that it is not concerned with control or manipulation of the powers confronted. Rather it means submission to, trust in, and adoration of, what is apprehended as the divine nature of ultimate reality.”
—Joachim Wach (1898–1955)
“I think it a much wiser thing to secure for the thousands of mothers in this State the legal control of the children they now have, than to bring others into the world who would not belong to me after they were born.”
—Susan B. Anthony (1820–1906)
“I am the center of the world, but the control panel seems to be somewhere else.”
—Mason Cooley (b. 1927)
