SECOND ORDER SYSTEM OF RLC ON MATLAB
Numerically solving second-order RLC natural response
Apr 29, 2016Numerically solving second-order RLC natural response using Matlab. It was unclear to me, but fortunately I passed. Recently I revisited the subject of RLC natural response again because I wanted to analyze the performance of a step up transformer based high voltage generator. For that reasons, I needed to derive RLC characteristic equations,..

Bandpass RLC NetworkAnalyzing The Frequency Response of The CircuitAnalyzing The Time Response of The CircuitInteractive GuiThe following figure shows the parallel form of a bandpass RLC circuit: Figure 1: Bandpass RLC Network transfer function from input to output voltage is:The product LC controls the bandpass frequency while RC controls how narrow the passing band is. To build a bandpass filter tuned to the frequency 1 rad/s, set L=C=1 and use R to tune the filter band.See more on mathworksThe Bode plot is a convenient tool for investigating the bandpass characteristics of the RLC network. Use tf to specify the circuit's transfer function for the valuesNext, use bode to plot the frequency response of the circuit:As expected, the RLC filter has maximum gain at the frequency 1 rad/s. However, the attenuation is only -10dB half a decade away from this frequency. To get a narrower passing band, try increasing values of R as follows:The resistor value R=20 gives a filter narrowly tu..See more on mathworksWe can confirm the attenuation properties of the circuit G2 (R=20) by simulating how this filter transforms sine waves with frequency 0.9, 1, and 1.1 rad/s:The waves at 0.9 and 1.1 rad/s are considerably attenuated. The wave at 1 rad/s comes out unchanged once the transients have died off. The long transient results from the poorly damped poles of the filters, which unfortunately are required for a narrow passing band:See more on mathworksTo analyze other standard circuit configurations such as low-pass and high-pass RLC networks, click on the link below to launch an interactive GUI.

Time Response OverviewFrequency Response OverviewStabilitySystem OrderFirst-Order SystemsSecond-Order SystemsThe time response represents how the state of a dynamic system changes in time when subjected to a particular input. Since the models we have derived consist of differential equations, some integration must be performed in order to determine the time response of the system. For some simple systems, a closed-form analytical solution may be available. However, for most systems, especially nonlinear systems or those subject to complicated inputs, this integration must be carried out numerically..See more on ctmsnhAll the examples presented in this tutorial are modeled by linear constant coefficient differential equations and are thus linear time-invariant (LTI). LTI systems have the extremely important property that if the input to the system is sinusoidal, then the steady-state output will also be sinusoidal at the same frequency, but, in general, with different magnitude and phase. These magnitude and phase differences are a function of the frequency and comprise the frequency response of the system..See more on ctmsnhFor our purposes, we will use the Bounded Input Bounded Output (BIBO) definition of stability which states that a system is stable if the output remains bounded for all bounded (finite) inputs. Practically, this means that the system will not "blow up" while in operation. The transfer function representation is especially useful when analyzing system stability. If all poles of the transfer function (values of for which the denominator equals zero) have negative real parts, then the system is..See more on ctmsnhThe order of a dynamic system is the order of the highest derivative of its governing differential equation. Equivalently, it is the highest power of in the denominator of its transfer function. The important properties of first-, second-, and higher-order systems will be reviewed in this section.See more on ctmsnhFirst-order systems are the simplest dynamic systems to analyze. Some common examples include mass-damper systems and RC circuits. The general form of the first-order differential equation is as follows(1)The form of a first-order transfer function is(2)where the parameters and completely define the character of the first-order system. DC GainThe DC gain, , is the ratio of the magnitude of the steady-state step response to the magnitude of the step input. For stable transfer functions, the Fi..See more on ctmsnhSecond-order systems are commonly encountered in practice, and are the simplest type of dynamic system to exhibit oscillations. Examples include mass-spring-damper systems and RLC circuits. In fact, many true higher-order systems may be approximated as second-order in order to facilitate analysis. The canonical form of the second-order differential equation is as follows(4)The canonical second-order transfer function has the following form, in which it has two poles and no zeros.(5)The parame..See more on ctmsnh
