A global power system transient stabilizer and voltage regulator is proposed in this paper. Two independent controllers i.e. transient controller and
voltage regulator are designed. In order to design\ voltage regulator we use simple neuro controller and for transient stabilizer we use Neural PSS. The final control action is the sum Neural PSS and neuro-voltage regulator. To achieve the global control action that guarantees both transient stability and voltage regulation, we used a membership function that was a function of measurable parameters of the system
