Abstract

A new method for the design of self-tuning adap­ tive lead-lag compensators is developed . The appli­ cation of this method to a nonlinear robot system, where a linear control theory has not been success­ ful, is presented . The self-tuning block uses a set of linear algebraic equations to solve for compen­ sator paramet ers. This control strategy takes into account the nonlinear terms of the system and the application of this method reduces the manufactur­ ing costs of automatic control systems that have high accurae.y and perform ance.
