ABSTRACT
Control system is a collection of elements and operations that works together to accomplish a unique task, which are measurement, control, and actuating. A good performance of this system is based on a good signal transmitting between their components. One of these main signals is called "control signal", which actuate the actuator to perform the control task. Due to some limitation of the actuator; the problem attended with the control action is how to keep it within the actuator limits to avoid the nonlinearity saturation phenomena. Therefore to achieve the high performance of the system, the control signal (control action) should be regulated instantaneously with the process output (stability of the system) in control system design. This paper presents simulating two cases of study, which are temperature and level control processes. These processes are controlled by a parallel PID controller and applying some modification techniques that are used to enhance the control signal which is essentially to fortify the actuator from the saturation phenomena. The modification techniques are based on repositioning the controller terms of the conventional parallel PID structure without any change in the tuned controller parameters. The outcome of the paper will help interested researchers in the control engineering area to select a suitable PID structure to design a perfect control system.
