Three op-amp Instrumentation amplifier circuit simulation using proteus

Dear all hand

As iam said before that theorically we can build our our instrumentation use op-amp. But its very challenging to simulate our instrumentation amplifer before we make it real. As usual we use proteus isi to build and to simulate our instrumentation amplifer .

Very important for us to use ideal op-amp in build instrumentation amplifier circuit that we want to simulate

What we need is:

1. 3 ideal op-amp
2. 6 ideal resistor
3. 1 Vsine
4. One potentio

And we arrange components above become three op-amp instrumentation circuit below :

The input and output relationship of the instrumentation amplifier above is :

Applying ohm law to R1 gives :

And we can rearrange equation above become :

And finally we get the output :

In this simulation we take R4= R5 .

To view output and input of this instrumentation amplifier we use oscilloscope (located at left bar of Proteus Isis)

Set V1 (sine ) at 4mV and 10 hz , and run simulate , the simulation result depicted below :

PID (Proportional Diferential Integral) Analog Controller Circuit Project based on-amp using Simulation With Proteus

Finally i finished my job, designing PID analog controller circuit using op-amp. For design work, i use proteus as CAD /CAE tool. And Proteus didn't make me disappointed, even idn't verivy the result matematically. Below the circuit :

I use ideal op-ap to contruct this analog PID controller circuit. But if you want to change analog PID controller circuit become more realistic , you just change the ideal op-amp in analog pid controller circuit with real world p-amp such of Lm 341.
We can simulate analog PID controller circuit with certain set point , below is the result figure :

I use set point at about 6,4 V to simulate analog PID controller circuit, and a dc motor as plant
