MRAC-2v3-0    The MRA-2v3-0 Model Reference Adaptive (MRA) Controller performs where a PID controller is inadequate for the task at hand. In many control applications where plant dead time (delay) is significant, the ubiquitous PID controller fails to perform its task adequately if at all. Plants can be classified as either close or loosely coupled systems. The combination of an electric motor and a rotor position sensor can be classified as a closely coupled feedback systems. An electric oven and thermal sensor however can be classified as a loosely coupled feedback system. This is because heat from the heating element takes significant conduction and convection time (delay) to reach the thermal sensor. MRA controllers can provide superior performance in Distributed Bragg Reflector (DRB) Laser stabilization, precision temperature control, vibration control and platform stabilization applications.
    The MRAC-2v3-0 is an ANSI C, hand coded programmable dual loop Model Reference Adaptive Controller implementation on a 45MHz Freescale ARM Cortex M3, MKL25Z128VLK4 MCU. With a sample rate fs=1kHz, the closed loop bandwidth is 5Hz. The algorithm can be ported to MCU's with higher operating frequencies to achieve greater closed loop bandwidths.
