On the design of sliding mode control schemes for quantum resonant converters

The design of sliding mode control schemes for quantum resonant converters is introduced hy means of two different approaches. First, an easy-to-use procedure for devising nonlinear control structures is established, using Lyapunov´s well-known stability criteria. Second, an alternative method that provides linear sliding surfaces is also developed, considering reaching, existence, and stability conditions. The application of both control design techniques is illustrated in detail by means of three selected examples. The advantages and drawbacks of the resulting control circuits are examined. Simulation and experimental results corroborate the expected features of the close-loop quantum converters
