1. MRPID controllers are more robust and provide better performance than FOPID and PID controllers.

2. MRPID controllers are able to handle non-linear systems with greater accuracy than FOPID and PID controllers.

3. MRPID controllers can be tuned more accurately than FOPID and PID controllers, allowing for better control of the system.

4. MRPID controllers are able to handle multiple inputs and outputs, making them suitable for complex systems with multiple variables.

5. MRPID controllers can be used in a variety of applications, including process control, robotics, automotive systems, and aerospace applications.
