Hello I am new to use MATLAB & I am working on sensorless vector control of induction motor, I found this code over internet for the same, but i am unable to understand it. will anyone explain it?

main file is aci3_4_m.m, but I know that predictor-corrector method is used in aci.m but how constants(K1-K10)is calculated and how that formula is derived that I am unable to understand. and same problem with aci_fe.m & aci_se.m in which how constants (K1_fe-K8-fe) & (K1_se-K4-se) is calculated and how the formula is derived? and simulation section of aci3_4_m.m is unable to understand. and also explain code of pid_reg3.m, & ramp_gen.m?

you can also add comments within the m files, and you can also give me reference for this.

Thank you.

Hey, I can help you understand this code but do you have the block diagram of this code ? because then only it is possible to explain. If not, you can tell me which website you got this code from?
