Algebraic decoupling synthesis is investigated and related to the Mark III-PSV-SOC philosophy of control. It is shown that feedback decoupling as opposed to open-loop network decoupling can be accomplished by feeding back fewer variables than a full state vector of the system. Reduction of the number of state variables fed back for decoupling places a restriction on the closed-loop poles which can be arbitrarily specified. A synthesis method for trading networks for state variable measurements is described. The method is illustrated in the decoupling control of airspeed and pitch attitude for a KC-135 model during approach. It is used to obtain a compensation function for use with the Mark III-PSV devices. Simulation results are presented. Author
