smart home is composed of several controllers with different plants in control. if each controller works independently, without considering the mutual effect of the others in the control process, the whole system could definitely not converge to an optimum desired status and may not ever reach the demanded condition. the function of different controller system may has conflict in some condition...

today there are different vibration isolators used in industries according to the weight and excitation frequency of the machines which have vibration. one of them is air spring which is in two types: convoluted air spring and membrane air spring. convoluted air springs are used to control vibrations in low frequency (usually lower than 10 hz) and the membrane ones are used in high frequency (u...

This paper addresses the issue of actuator selection for active flow control by proposing a novel method built on top reinforcement learning agent. Starting from pre-trained agent using numerous actuators, algorithm estimates impact potential removal value function, indicating agent's performance. It is applied to two test cases, one-dimensional Kuramoto–Sivashinsky equation and laminar bidimen...

Machine learning frameworks such as Genetic Programming (GP) and Reinforcement Learning (RL) are gaining popularity in flow control. This work presents a comparative analysis of the two, bench-marking some their most representative algorithms against global optimization techniques Bayesian Optimization (BO) Lipschitz (LIPO). First, we review general framework model-free control problem, bringin...
