In this paper the application of PID control in the student projects such as robotic car or robotic arm will be considered. The objective is to direct a robot car to follow a predefined path or a robotic arm reaches the preset target within the minimum time and error.
PID stands for Proportional–Integral–Derivative. It is a closed loop feedback control which is commonly used in an industrial system. A PID controller continuously calculates an error as the difference between a desired set-point and a measured process variable and applies a correction based on proportional, integral, and derivative terms denoted by P, I, and D. The PID controller attempts to minimize the error over time by adjustment of a variable, such as the position of a robot arm. For example, if the current output is not sufficiently strong, the integral of the error will accumulate over time, and the controller will respond by applying a stronger action. Derivative control accounts for possible future trends of the error, based on its current rate of change. Some applications may require using only one of (P, I, D). This is achieved by setting the other parameters to zero. PID controller can use two combination of (P, I, D) or all three terms to provide the appropriate system control. PI controllers are fairly common, since derivative action is sensitive to measurement noise, whereas the absence of an integral term may prevent the system from reaching its target value.
In this paper the result of PID controller in the student projects such as robotic car will be analyzed. The Results are based on the application of proportional, integral, and derivative control. A MATLAB program for calculating PID values will be presented.
