The invention discloses a controllable stable current source, belongs to the control and adjustment field, and particularly relates to improvement of an existing controllable stable current source. The controllable stable current source can be used to accurately control a high power and large damping force magneto-rheological damper. The controllable stable current source comprises a judgment module, a field effect tube, a voltage stabilizer, an optical coupler, a single chip computer, a triode, an amplification circuit, a rectifying and filtering circuit and an adjustment circuit, and is characterized in that the judgment module, the field effect tube, the voltage stabilizer, the optical coupler, the single chip computer and the triode are sequentially connected, the optical coupler is connected with the amplification circuit, and the single chip computer and the rectifying and filtering circuit are connected with the adjustment circuit.
