A quadrotor is a multirotor helicopter, boosted by four rotors. In contrast to fixed-wing aircraft, quadrotors are categorized as rotorcraft, since their lift is produced by a set of rotors. The usage of quadrotors has increased in recent years in civilian and military operations. They are adaptable during vertical takeoff and landing and have stability when hovering. Additionally, quadrotors have low power consumption and are unobtrusive.
The many important applications of quadrotors include delivery and monitoring. A quadrotor can fly in an autonomous and non-autonomous manner with use of methods using the proportional integral derivative (PID) and linear quadratic regulator (LQR), sliding mode control, and fuzzy control. Such methods stabilize the quadrotor through flights. The aim of most controllers is to eliminate the error which is the difference between a measured value (measured states by sensors) and a desired set-point (desired states). The “error” can be minimized by adjusting the control inputs and the speed of the motors, in an iterative manner. This chapter illustrates key applications, and further the modeling and control of quadrotors is described in brief. Two cases of studies are presented, the first of which deals with the design of PID control for precise positioning of delivery quadrotors, and the second entails the design of multiple model adaptive control (MMAC) of the quadrotor.
