Application of robotic manipulators for grinding purposes may cause unreasonable behavior during grinding of uneven surfaces such as damaging workpiece surface, or following undesired roughness of the surface depending on the control strategy. This paper presents an adaptive control strategy which is a combination of a closed loop position control to track the desired path, an open loop force control...
High penetration levels of stochastic renewable sources introduce variability into power systems that result in voltage and frequency regulation difficulties. As the cost of fossil fuels increase and governments mandate large renewable-energy portfolios, new engineering approaches will be necessary to compensate for this variable generation. Today renewable energy penetration levels are often limited...
IEEE 802.15.4 is regarded as one of the most suitable communication protocols for cyber-physical applications of wireless sensor and actuator networks. This is because this protocol is able to achieve low-power and low-cost transmission in wireless personal area networks. But most cyber-physical systems (CPSs) require a degree of real-time and reliability from the underlying communication protocol...
This paper mainly investigates adaptive synchronization of complex Lü system with uncertain parameters. On the basis of Lyapunov stability theory, an adaptive controller for the synchronization of the complex Lü system is designed, and some parameter update laws for estimating the unknown parameters of the systems are also gained. The numerical simulations demonstrate the validity and feasibility...
