Regarding Perturb and Observe Implementatuion Using C block
Altair EmployeeIs it possible to implement Perturb and Observe algorithm using C block in PSIM?
Will following code work for Perturb and Observe algorithm in C Block?
If (Power_new-Power_old>0)
Vref=Vref+0.1;
else
Vref=Vref-0.1;
Is it correct to Equate V*I to Power_old by using one time step delay?

You will be able to implement your MPPT algorithm with the C block. I will not comment on the accuracy of your code.
Some comments about the c block,
Static variables will only be initialized once at the beginning and can be used to hold remember a value from a previous timestep. A regular variable definition will cause the variable to be re-initialized every time step. Also the c block will run at every time step, if you want to define a sampling rate for the c block you should put a ZOH element on all of the inputs to the c block which will force it to execute at the defined rate.0 -
Is it possible to use sample and hold element for all the inputs to C block? Will it force C block to execute at the defined rate?

use the ZOH hold block on the inputs to the c block to force the c block to execute at a defined sample rate.
Do NOT USE the sample and hold block to accomplish this, it needs to be the ZOH.
