Control Control system Error State Steady Steady state System

AI Thread Summary

Steady state error in control systems is analyzed through the relationship Ea(G1+D)G2=C, where C represents the closed-loop transfer function. The equation indicates how steady state error can be minimized by adjusting the system parameters. There is a discussion about potential contradictions between different interpretations of the steady state error equations. Clarifying these relationships is crucial for accurate control system design. Understanding these dynamics is essential for achieving desired system performance.

Hello,

I have a question about steady state error.

how can we get to the C?

I think it has to be Ea(G1+D)G2=C
which gives(R-NH)(G1+D)G2 / (1+(G1+D)G2H)=C

Hi,

Is there a contradiction between what you write and what the author writes ?

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
