CONCLUSION

The method of virtual analogue simulation has been described. It has been shown that each block diagram in the feedback control loop can be mapped into a corresponding circuit diagram or module. Modules with nonlinearity may also be included. For electrical engineering students who have some experience in using PSpice for learning electronic circuits, the only additional skill required is to obtain the schematic diagram from the transfer function of a block diagram. Once this is done, the rest follows the usual procedures for circuit simulation. The examples provided above have served to demonstrate that the VAS method is effective and easy to apply.
