Instructional Objectives At the end of this lesson, the student should be able to • Distinguish with examples the difference between sequential control and continuous process control. • Identify three special features of a process. Fwsim Keygen Download For Idm there. • Differentiate between manipulating variable and disturbance.

• Distinguish between a SISO system and MIMO system and give at least one example in each case. • Develop linearised mathematical models of simple systems. • Give an example of a time delay system. • Identify the parameters on which the time delay is dependent. • Sketch the step response of a first order system with time delay. • State and explain the significance of transfer function matrix. Introduction We often come across the term process indicating a set up or a plant that we want to control.

Thus by a process we may mean a unit of chemical plant (say, a distillation column), or a manufacturing system (say, an assembly shop), or a food processing industry and so on. We may want to automate the process; we may also like to control certain parameters of the system output (say, level of a tank, pressure of steam etc.). Broadly speaking, there could be two types of control; we might want to carry out.

The first one is called sequential control, where the control action is carried out in a sequence. A good example for this type of operation could be in an automated car manufacturing system, where the assembly of parts is carried out in a sequence (on a conveyor line). Here the control action is sequential in nature and works in a preprogrammed open loop fashion (implying that there is no feedback of the output signal to the controller).

Programmable Logic Controller (PLC) is often used to carry out these operations. But there are cases, where the control action needed is continuous in nature and precise control of the output variable is required. Take for example, the drum level control of a boiler. Here, the water level of the drum has to be maintained within a small band, in spite of variations of steam flow rate, steam pressure etc. This type of control is sometimes called modulating control, as the control variable is modulated to keep the process variable at a constant value.
