An intra-cavity optical parametric oscillator based on RbTiOPO (RTP) crystal simultaneous output eye-safe light and mid-infrared wavelength light was demonstrated. An laser diode end pumped acousto-optic Q-switched Nd:YAlO laser at 1.08 μm was used as the pump source. At an incident pump power of 8.7 W and a pulse repetition frequency of 20 kHz, total average output power up to 1.12 W (890...
In order to solve the problem that model predictive control, MPC, is difficult to apply to the large scale system or fast dynamic system, in this paper, we describe a new fast online optimization predictive control method. This method is to exploit the structure of the QPs that arise in MPC, reorder the appropriate variable and use the advanced interior-point to improve the control performance and...
In order to estimate the packet dropout in Networked Control Systems (NCS), this paper presents an explicit model predictive control. We firstly transform the model for networked control systems with data packet dropout into piecewise affine form. Then we solve a constrained optimal control problem with PWA model. By using the method of explicit predictive control, which is based on multi-parametric...
The effluent of secondary sedimentation tank in a petro-chemical factory was treated with eco-ponds. The eco-ponds was constituted by the facultative pond, aerobic pond and hydrophyte pond, which was enhanced by the eco-concrete revetment, filter and floating bed of aquatic plants. Running results indicated that, HRT=45h, the removal rate for COD, TN and TP in the treated water was 28.3%–49.4%, 29...
