This paper proposes smart Field programmable gate array (FPGA) based DC-DC buck converter control system design platforms using Xilinx System Generator and hardware descriptive language (HDL) Co-simulator. In traditional way of FPGA based implementation of control system, interaction occurs between the controller and system only in the final stage of(More)
In this paper we investigate a particular behavior of autonomous mobile robots for obstacle avoidance, where the geometry of obstacle is non convex in nature. The detection and avoidance of the obstacle is done by means of robot exploration in the given environment. This behavior is modeled using Hybrid Cellular Automata controllers. Finally the validation(More)
Being an inherently unstable system, active magnetic bearing, with its envisaged widespread applications, is a potential research area in today's scenario. So far many controllers including the H- Infinity controller has been developed but a generalized design is lacking. In this paper a generalized design of H- infinity controllers for Magnetic bearings is(More)
In recent years researches in hybrid system dynamics and control strategies have become very prominent because most of the systems show hybrid behavior (continuous and discrete) in their dynamics. In this work authors have considered a three-tank autonomous hybrid system for the investigation. Implementation aspects of the model based control scheme and a(More)
Extended Kalman Filter (EKF) and Unscented Kalman Filter (UKF) based controllers for a class of hybrid systems, namely autonomous hybrid system (AHS), are proposed in this work. The stability in the performance of EKF and UKF based controllers were analyzed using experimental setup of hybrid three-tank system under variety of real-time uncertainties and(More)
The self-tuning regulator (STR) is a popular adaptive control algorithm. A high-performance computer is required for its implementation due to the heavy online computational burden. To extend STR for more real-time applications, a parallel hardware implementation on a low-cost reconfigurable computer is presented. The hardware was incorporated with(More)
