Abstract
Control engineering had been the core of all engineering fields all the time. As the name depicts, control of different parameters of various industrial or commercial equipment like plants, vehicles, aircrafts and etc is obtained. Robust and optimal control of these equipments plays a vital role. This paper presents a design of H2 and H∞ control for a Twin Rotor System (TRS). TRS is a multi input multi output (MIMO) nonlinear system. The main objective is to control the angular position of the lever bar of TRS. It is having strong coupling between inputs and outputs. The model is first linearized and then controllers are designed to control the positions of lever bar. Simulations are made in MAT- LAB/SIMULINK. Model parameters are also provided in the end.

Summary
The question of Multi-Input-Multi-Output (MIMO) control has always been a thought-provoking sub-field surrounded by the field of control engineering. Among the systems that involve MIMO control, the helicopter rises out as one of the striking models This kind of aircraft needs two rotors, spinning in perpendicular planes, cannot depend on Single-Input-Single-Output controllers to steer in the deep space. Its operation approaches a helicopter but the angle of attack of the rotors is fixed, and the aerodynamic forces are regulated by changing the speed of motors. The TRS comprises of a beam centered on its core in such a way that it can gyrate freely both in the horizontal and vertical planes At both ends of the beam, there are rotors (main rotor and tail rotor) steered by DC motors. It comprises of a vertical axis A on which a lever arm L is connected by a cylindrical joint using an L shaped link. A weight is mounted on an adjustable position towards the tail rotor
