Application of Simulink in circuit analysis

Features and applications of Simulink Toolboxes in Matlab are introduced,and its blocksets relating to circuit analysis and calculation are explained,such as Simulink,SimPowerSystems and Extra Simulink.With DC steady-state circuits,transient state circuit and sinusoidal steady-state circuit in the circuit curriculum as examples,the way to apply Simulink to circuit modeling and further analysis and calculation is investigated,including the current of DC resistance circuit,the voltage,current and independent source power of DC resistance circuit containing VCCS(Voltage Controlled Current Source),the inductance current and voltage source current of first-order inductance circuit,and the branch current,capacitance voltage and source complex power of sinusoidal steady-state circuit.Some techniques are given.Simulation results are accordant with those of theoretic analysis,which provides a reference for developing computer-aided analysis in circuit curriculum.
