Introduction: The PID controller has several important functions: it provides feed- back; it has the ability to eliminate steady state offsets through integral action; it can anticipate the future through derivative action. PID controllers are sufficient for many control problems, particularly when process dynamics are benign and the performance requirements are modest. PID controllers are …
Introduction: Today in this article we learn about what is a pneumatic system. Fluid power is an applied science dealing with ways of using pressurized gas (pneumatics) or liquid (hydraulics) for doing work. Hydraulic systems use oil, which is pumped into hydraulic cylinders or hydraulic motors and made to do work. Pneumatic systems use a …
Introduction: A matter exists in either the solid state or the fluid state. The fluid state is further divided into the liquid and the gaseous states. In fact the same matter may exist in any one of the three states .solid, liquid and gaseous. For example water, which ordinarily occurs in a liquid state, may …
Introduction: A Variable Frequency Drive (VFD) controls the speed of a motor, specifically a three phase motor. To better understand a VFD, let’s examine the motors they control. Most commercial HVAC systems require powerful motors, and often operate on a three phase power (The standard method for electric power distribution systems because of its efficiency). …
Introduction: Today in this article we learn about Different Types of Industrial Automation Systems. Automation can generally be defined as the process of following a predetermined sequence of operations with little or no human labor, using specialized equipment and devices that perform and control manufacturing processes. Automation in its full sense, is achieved through the …
Introduction: What Is Actuator : In industrial control systems, an actuator is a hardware device that converts a controller command signal into a change in a physical parameter. The change in the physical parameter is usually mechanical, such as a position or velocity change. An actuator is a transducer, because it changes one type of …
Introduction: A wide variety of sensors are available for collecting data from the manufacturing process for use in feedback control. A sensor is a transducer, which is a device that converts a physical variable of one form into another form that is more useful for the given application. In particular, a sensor is a device …
What is Industrial Automation: Automation can be defined as the technology by which a process or procedure is accomplished without human assistance. It is implemented using a program of instructions combined with a control system that executes the instruction To automate a process, power is required, both to drive the process itself and to operate …
