A PID controller can serve as an alternative controller in wireless communication. Consider the system in Figure 6.18. Ignore cost function calculations. Try to set up good parameter values for the PID controller. Gain of the integral controller is set = 0. The derivative gain is set to a small value. Start with proportional gain that is below one. Increase the derivative gain only slightly. Experiment with control parameters to understand how difficult it is to determine two control parameters in a satisfactory manner.
