This paper presents a hybrid control strategy, combining Radial Basis Function (RBF) network with conventional proportional, integral, and derivative (PID) controllers, for the greenhouse climate control. A model of nonlinear conservation laws of enthalpy and matter between numerous system variables affecting the greenhouse climate is formulated. RBF(More)
The traditional tuning scheme of proportional, integral, and derivative (PID) controller parameters usually lay more emphasis on control performances than economic profits. As a result, the corresponding control performance is improved, but such case may lead to high production costs. In this paper, a new tuning methodology for multiple PID controllers from(More)
In this paper, a novel anti-windup scheme is proposed for the prevention of proportional–integral– derivative (PID) controller integrator saturation by introducing a changing integration rate into the integral term. The method can achieve smooth adjustment for the integral term in a stepless way according to the error size, and it is easily implemented and(More)
Noble gases seem to have no significant effect on the anesthetic targets due to their simple, spherical shape. However, xenon has strong narcotic efficacy and can be used clinically, while other noble gases cannot. The mechanism remains unclear. Here, we performed molecular dynamics simulations on phospholipid bilayers with four kinds of noble gases to(More)
In this paper, we present a novel technique integrating logic simulation and Boolean satisfiablity (SAT) for verifying the designs with black boxes, and generalize this technique to improve the accuracy of design error diagnosis. This technique uses intelligent set of vectors instead of randomly generated vectors for logic simulation during black box(More)
Recent experiments have reported that the fragment of viral protein R (Vpr), Vpr13-33, can assemble and change its conformation after adsorbed on graphene oxide (GO) and then reduce its cytotoxicity. This discovery is of great importance, since the mutation of Vpr13-33 can decrease the viral replication, viral load and delay the disease progression.(More)
