Proportional Control Demo using Slider in Tkinter
Understanding Proportional Control:Proportional control is a basic feedback control technique that adjusts the control signal proportionally to the error between a desired setpoint and the process variable. The process variable represents the current state of the system being controlled. By continuously monitoring and adjusting the control signal, the system strives to minimize the error and…
