# Is there any other controller than PID Controller?

I have been given a Project to search for a controller having better transient response than PID Controller. I searched but I didn't find any research paper on it. All are talking about improving PID's transient response but I am unable to find any other Controller with the better transient Response. Can anyone share comparative analysis between the aforementioned controllers Or a Research Paper? Or can someone list controllers?

P.S: I'm new in Control Theory field.

Since you are new to Control Theory as you say and also new to the forum, I will give you some hints on what you are asking. However, in the future you should initially do your own search and if it is essential ask here providing what you have done so far and what exactly you didn't understand and confuses you. I encourage you to read also this thread on how to ask good questions:

A controller is a structure which a designer implements in order to be able to force certain behavior to a specific physical system. The PID-Controllers are probably the most known of these structures since they are widely used in the industry due to their relatively easy design procedure (although I believe that there are numerous aspects to be taken into consideration when designing and tuning a PID controller) and because they can even be tuned (selection of the $$K_p,K_d,K_i$$ gains) without the knowledge of the mathematical model whih describes the real system. However, there is a vast majority of controllers which an engineer can choose to implement like lead-lag compensators, state feedback controllers (full state or dynamic state), linear quadratic regulator and so many more. To conclude, yes there are many other controllers which you can choose to implement.
