Some applications may require using only one or two modes to provide the appropriate system control.

The response of the controller can be described in terms of the responsiveness of the controller to an error, the degree to which the controller overshoots the setpoint and the degree of system oscillation.
Note that the use of the PID algorithm for control does not guarantee optimal control of the system or system stability.
However, from a control perspective, physical interactions between the UAVs and the payload during collaborative transportation present challenges in terms of stability and accurate trajectory tracking.
In this paper, a leader-follower approach is implemented.The control scheme proposed in this research addresses this major limitation.In this research, a Force Feedback Controller (FFC) is used to control the follower UAV.The weighted sum of these three actions is used to adjust the process via a control element such as the position of a control valve or the power supply of a heating element.By tuning the three constants in the PID controller algorithm, the controller can provide control action designed for specific process requirements.The leader UAV uses a Proportional, Integral and Derivative (PID) controller to reach the desired goal point or follow a prede? Traditionally, a Position Feedback Controller (PFC) has been used in literature to control the follower UAV.PFC takes the feedback of leader UAVs position to obtain the desired trajectory for the follower UAV which is then tracked using a traditional PID controller.A proportional–integral–derivative controller (PID controller) is a generic control loop feedback mechanism (controller) widely used in industrial control systems.A PID controller attempts to correct the error between a measured process variable and a desired set point by calculating and then outputting a corrective action that can adjust the process accordingly and rapidly, to keep the error minimal.Note: Due to the diversity of the field of control theory and application, many naming conventions for the relevant variables are in common use.A familiar example of a control loop is the action taken to keep one's shower water at the ideal temperature, which typically involves the mixing of two process streams, cold and hot water.
