The usual bench power supply seen in laboratories have the feature to set a limit current. Very handy for e.g. LED testing: you set the current to max 20mA, the voltage to 5V and connect the LED without a resistor. The supply limits current and displays the voltage for it.
These devices usually have a remote control feature; the current sensing and controlling is done in the device.

25V, 3A output capability with an analogue controller requires large heat sinks; building a switching controller could be difficult. And you need the control loop design.
