Temperature Control Using Hybrid Control with MRAC and ECS into a MIMO Microwave Heating Process

摘要

Microwave heating is an advanced heating technique in which heat is generated inside the material, but thermal runaway phenomenon is still the major challenge of the microwave heating process. The application of a hybrid temperature control structure with model reference adaptive control (MRAC) and expert control system (ECS) to a multi-input multi-output (MIMO) microwave heating process is addressed in this paper. Two input variables, microwave power and ambient temperature, are considered to be regulated and controlled as the output variables to track the desired temperature profiles. Simulation tests are carried out in MIMO configuration to validate that the hybrid controller with MRAC and ECS achieves better control performance than the sole MRAC strategy.
