Transient Response of Control SystemAs the name suggests transient response of control system means changing so, this occurs mainly after two conditions and these two conditions are written as follows-Condition one : Just after switching ‘on’ the system that means at the time of application of an input signal to the system.Condition second : Just after any abnormal conditions. Abnormal conditions may include sudden change in the load, short circuiting etc.Steady State Response of Control SystemS

Signal Flow Graph DefinitionA signal flow graph simplifies control system diagrams by using nodes and branches instead of blocks and summing points.Rules for Drawing Signal Flow Graph The signal always travels along the branch towards the direction of indicated arrow in the branch. The output signal of the branch is the product of transmittance and input signal of that branch. Input signal at a node is summation of all the signals entering at that node. Signals propagate through all the branches

Digital Data DefinitionDigital data in control systems consists of discrete or sampled data that represents continuous signals in a digital format.Sampling ProcessSampling is the conversion of analog signals to digital signals using a sampler, which switches ON and OFF.The sampling process converts analog signals into digital signals using a switch, called a sampler, that turns ON and OFF. For an ideal sampler, the output pulse width is very small (almost zero). In discrete systems, Z transforma
