Discrete Controller Design for A Hybrid Three Tank System

Systems in which the dynamical behaviour evolves based on the interaction between the continuous dynamics and the discrete dynamics, present in the system, are called hybrid systems. Traditionally such systems were analysed either as purely continuous or purely discrete systems. The interactions between discrete and continuous systems in today’s technological problems have become so important that hybrid modelling of such systems is called for. In this paper a discrete controller is designed for such a hybrid system. Hybrid modelling technique is used to model the hybrid three tank systems. The hybrid model is simulated in SIMULINK and STATEFLOW is used to design the discrete controller
