In this article, the problem of voltage and frequency stability in a hybrid multi-area power system including renewable energy sources (RES) electric vehicles has been investigated. Fractional order systems have used to design innovative controllers for both load control (LFC) automatic regulator (AVR) based on combination fractional proportional-integral proportional-integral-derivative plus d...

New technological developments in space engineering and science require sophisticated control systems with both high performance and reliability. How to achieve these goals against various uncertainties and off-nominal scenarios has been a very challenging issue for control system design over the last years. Several efforts have been spent on control systems design in aerospace applications, in...

The tuning of Linear Quadratic regulator (LQR) controllers is a challenge for researchers and plant operators. This paper presents a optimization and comparison of time response specification between Traditional ZN Tuning & Modified ZN Tuning controllers with Linear Quadratic Regulator (LQR) for a speed control of a separately excited DC motor. The goal is to determine which control strategy de...

This report presents a method of controlling an unmanned ground vehicel (UGV) by employing hybrid control theory. The linear dynamics of the UGV near a straight path conform to modern linear quadratic regulator theory. Two different methods for regulation of the UGV on a straight track are analyzed. The first method employs the steering angle as an input, while the second employs the derivative...

This article develops a novel method based on the memetic algorithm for optimal feedback control design. The aircraft controllers are designed to produce desired handling qualities. The robust properties of the linear quadratic regulator are exploited to obtain the desired aircraft handling qualities with an output feedback constrained linear quadratic regulator subspace based on a cost functio...
