Steady State Error Solved Problems
Pushing the input transducer to the right how to reduce steady state error past the summing junction yields the general nonunity feedback system shown in steady state error control system example Figure 7.15(b), where and . Notice that unlike a unity feedback system, where , the error is not http://www.slideshare.net/leonidesdeocampo/lecture12me1766steadystateerror the difference between the input and the output. For this case we call the signal at the output of the summing junction the actuating signal , . If and have the same units, we can find the steady-state http://higheredbcs.wiley.com/legacy/college/nise/0471794759/justask/SNM07010.html error, . The first step is to show explicitly on the block diagram. Forming an equivalent unity feedback system from a general nonunity feedback system (Figure 7.15, Page 389) Take the nonunity feedback control system shown in Figure 7.15(b) and form a unity feedback system by adding and subtracting unity feedback paths, as shown in Figure 7.15(c). This step requires that input and output units be the same. Next, combine with the negative unity feedback, as shown in Figure 7.15(d). Finally, combine the feedback system consisting of and , leaving an equivalent forward path and a unity feedback, as shown in Figure 7.15(e). Notice that the final figure shows explicitly.
