Abstract

Stability and robustness in control systems are commonly achieved by designing signal compensators and filters composed of the system's passive parameters in analog or digital form. The passive compensators are generally used to frequency shape the active state variables in the control system. If wideband loops are required when the plant contains non-linearities and high order dynamics, the use of fixed frequency, passive parameter compensators to obtain stability may not be tractable. In such systems, however, control stability can be achieved by manipulating the active state variables themselves. This paper presents the general concepts of State Equalization, a control system stabilization technique which utilizs the differing characteristics of the active state variables to achieve the desired stability in systems containing non-linear resonant plants. The technique, conceived in the mid seventies, is used in several fielded weapon systems. One of the applications is used to illustrate the use and advantages of the State Equalization technique.
