Hi,
I need some help with my PID control loop. My question is how can you get a compensator to map and output a certain range of values? i.e. for each error, i would like to map to some voltage between 1 to 10 volts, which are fed into another block in my power supply design.
So far, i have a plant which sends an output voltage value to be compared with a set point. the combination of these two is used to create an error voltage, which is fed into a PID transfer function. The resulting output is some number (i assume it to no longer be the error voltage), which is really small (i.e. in the range of 1*10^-3) How can i map these values to a voltage to be fed into the next stage of my power supply? i.e. if PID output is 0.001, then, set value to 2.7volts.
in summary, how can i change my compensator or what should i add after my compensator such that my actuator receives the correct range of input? I don't think i can just scale this value (e.g. increase the gain of my compensator). Any ideas?
