In this study, the design, implementation and experimental evaluation tests of a Takagi–Sugeno power system stabiliser (TSPSS) controller is presented. The controller was designed in order to provide a good damping for dominant electromechanical oscillations in power systems for the set of allowed operating conditions. In the proposed TSPSS controller, such requirement was accomplished by implementing a supervision scheme which performs the adaptation of the TSPSS parameters at each sample time, according to the current detected plant operating condition. The TSPSS controller has been implemented as a microcontroller‐based embedded system and its performance was assessed by performing experimental tests in a laboratory scale (10 kVA) power system as well as in field tests performed in a large (350 MVA) generating unit, at Tucuruí Hydroelectric Power Plant. The experimental results also show the good performance of the TSPSS to cope with varying plant operation condition.
