A class of nonlinear plants characterized by multiple control channels is considered, where the same output objective can be achieved through different combinations of control inputs. As a representative example, a doubly-fed inductor motor is analyzed, for which six control variables are available: two voltage amplitudes, two frequencies, and two controllable phase shifts. These inputs enable regulation of the motor’s angular velocity, r otation angle, and electromagnetic torque. For the synthesis of control laws, linear -system theory is employed with parameters fixed at values defined by the steady -state operating point of the nonlinear plant. The proposed approach utilizes the redundancy of control inputs, since variations in speed or position can be achieved with different combinations of control variables. Although operating conditions change during regulation, which would normally require adaptation of cont rol-law parameters, in the proposed method these parameters remain constant. Instead, appropriate coordinated adjustments of supply frequency and voltage amplitude are selected to achieve the desired speed (proportional to the frequency difference) while keeping controller parameters unchanged.
