Controls are used when a slam seems possible and before the Blackwood
The principles :
  • A suit is controlled when there is no (or maximum 1) trick to lose on a lead in this suit.
  • Controls are always bid in an economic sequence : skipping one is a control denial.
  • When a suit is not controlled (by none of the players) the last player to bid gets back to the trump suit. It's a Stop.
  • No Blackwood if a control is missing.

 
Different control types
  • A void or a singleton are controls for a trump contract, obviously not in NT.
  • Aces and Ks are efficient controls in a trump or NT contract.
  • Aces and voids are 1st round controls, singletons and Ks are 2nd round controls
