Stability-equation method for multivariable feedback control systems with lead/lag compensators (Q581321)

The stability-equation method is extended to the analysis and design of multivariable control systems. The systems are first compensated by constant precompensating matrices, and then compensated by lead/lag compensators. The method can take into consideration integrity and asymptotic behaviour simultaneously. In addition, other considerations, such as high frequency alignment and low-interaction at high frequency, can be analysed. Numerical examples are given and comparisons made with other methods in the current literature.
