Usually, the design of control systems is based on proportional control. The main difference between a proportional controller and a proportional plus derivative controller is that the latter has a derivative section added. According to Cooper (2007), this derivative action is responsive to the rate of change of the error signal. In order to compare the two, it is important to examine the characteristics and mode of operation of each, as well as their industrial application.

Proportional Controller

Of all controllers used in control systems, the proportional controller is the most simple. In this method of control, the control system behaves in a manner that ...

An EMS controls the vehicle engine in response to both vehicle and engine inputs. It consists of an electronic control unit composed of a micro-processor with several electromechanical and electronic actuators and sensors. Sensor devices are used to monitor the vehicle engine and detect engine speed, lambda values, crank angle and other engine parameters. The electronic control unit determines the engine ignition time, the quantity of fuel and other engine parameters that keep the vehicle engine running. The ECU does this by use of input values that are calculated based on the inputs that originate from the sensors. Under this ...

Formation of bone during foetal development occurs through the process of ossification. This process is extremely important to proper bone length, density, and uniform skeletal formation. It is driven by a complex network of genes that code for signalling proteins whose function is to turn the ossification process on, off, or slow it down. Defects in these genes can cause problems with the ossification process, and can lead to conditions of skeletal dysplasia (improper formation of bone). One such condition is Achondroplasia, one of the most common forms of dwarfism, or congenital short stature (Lister Hill National Centre for Biomedical ...

In a control system, the interest is maintaining the system in a steady state irrespective of the input into the system. In achieving this aim, the system is designed to constantly check for deviations from this goal and apply the corrective measures to keep the system steady when there are deviations from the steady state. The device that ensures this desired output is a controller. The overall aim of using a controller in a system is thus to maintain the stability of such a system in the face of deviations (errors) from a desired output.

Controllers are used in a feedback system because of the need to ...

Communication is conveying of the message that carries meaning. In an effective communication setup, there must be a sender and the receiver. When the receiver of the message acts as the sender intended then, the process is effective. The receiver of the message is required to send feedback to show that the message was well conveyed. The cost of communication should be low enough. However, the noises that arise in most of the communication setup usually make most of the communication ineffective and in most cases costly.

Managers of all organizations have a responsibility to communicate effectively to the employees ...
