A Variable Structure System (VSS) is a type of dynamic control system that is designed to adapt its control strategy based on the current state of the system or the external conditions. The key characteristic of VSS is that it changes its structure or control law during operation, allowing it to maintain desired performance even in the presence of uncertainties, nonlinearities, or varying system parameters.
