Root locus techniques are used infrequently in the design of tachometer and acceleration feedback compensation, for feedback control systems. A root locus stability criterion is discussed, which has the capability of handling more than one variable coefficient in the characteristic equation. This stability criterion is applied to the analysis and design of tachometer and acceleration feedback compensation. The design of cascase compensation is attempted, and the difficulties of designing this type of compensation with the root locus stability criterion is found to be a useful tool for designing tachometer and acceleration feedback compensation for third order systems, and for certain fourth order systems
