Universal controller with fixed parameters is designed by derivatives balance method. Controller simultaneously can handle the problems of stabilization, adaptation , reference tracking and disturbance rejection for both linear and nonlinear systems.

Dear Musaab Ali
A universal controller allows you to control everything that's connected to your TV with the same remote. You can move through menus, power on/off and access most of the other options and choices that your original remote had.

Hi Dr Musaab Ali . It measures the output of a process and then manipulates the input as needed to drive the process variable toward the desired setpoint. A controller reacts to setpoint changes initiated by the operators as well as random disturbances to the process variable caused by external forces.

Kindly, see the following link too: https://uh.edu/~jhansen/Chapter%201/UniversalSystemsModel.htm
I think that this video will appeal to developers of air taxi control systems.
Your controller allows everyone to easily solve all the issues of stabilization and tracing control for linear and non-linear plants! The control theory for these systems needs to be modified to reflect your discovery.
Can we vadidate this control method for any physical system, because physical system has fixed coefficient (with some uncertainty). But the periodically time-varying coefficient system is considered in this method.
Remember, time-varying coefficient system is different thing rather than time-varying system.

- Interesting, and your method performs well for linear and nonlinear systems.
- In both videos, the linear system is considered, the first one is the 2*2 MIMO (meaning that two controllers are used for two outputs, which means one controller is employed for controlling one output), the second one is the SISO system (which also means, controlling one output using one controller.)
- can also we validate this for the SIMO system (meaning that we have to track many outputs by using only one control input)?

This is the perfect example of a SIMO System:
(One controller and two different outputs)
- Finally, this control method is great where one controller is used for one output as well as for MIMO.
- But this method can be extended for SIMO system, where we can control "n" output by using only one controller. (and it is the suggestion also)
- Because in the n*n MIMO system, where "n" controllers are used for "n" outputs, which means one controller is employed for controlling one output),, and same as for the SISO system which also means, controlling one output using one controller.
- This method can be extended to SIMO system, where we can control "n" output by using only one controller.
- Because the meaning of
SISO: one controller (input) and one output
MIMO: "n" controller (input) and "n" output. Here also equivalent meaning that one controller is being used for one output.
- Moreover, an over-actuated system is also a class of systems where the system has many controllers that are used for controlling a few outputs.
- Similarly, the SIMO (https://www.youtube.com/watch?v=IfyDISiw6mY) is also called the under-actuated system.
