Nowadays, with the improvement of buildings leakprofness and indoor decoration materials' widely use in sealing, household air quality has been the object of attention. So we combine the Zig Bee wireless communication technology with sensor detection technology and a set of multipoint real-time monitoring system of household air quality based on Zig Bee is designed. CC2530 chip microprocessor as the core, system adopt master-slave structure. Its sensor nodes from the machine collect air environmental data, air temperature and humidity sensor nodes to real-time transmission to the host gateway nodes and summary. Master machine combined with monitoring data to determine and display the whole household air quality status, so as to realize the state monitor alarm, and then take measures to improve air quality.

Organic Rankine Cycle (ORC) is an effective technology to recovery low grade waste heat from exhaust gas. Many advantages of ORC are high efficiency, simple system, low pressure of working to seal, environment friendly and so on. A novel control algorithm called Active Disturbance Rejection control (ADRC) is applied to vapor temperature control at the outlet of evaporator of organic Rankine cycle (ORC) system. The disturbances imposed on the waste heat recovery system are estimated through an extended linear state observer and then compensated by a linear feedback control strategy, it can eliminate disturbance via disturbance compensation independent of the accurate mathematical model of the plant. It is reliable, efficient and simple. Simulation examples demonstrate the simplicity of the design procedure and the good tracking performance.
In this paper, the organic Rankine cycle (ORC) in waste heat utilizing process is investigated. In order to study the performance of the ORC system, the method of mechanism analysis is applied in modeling. In order to...

In this paper, the organic Rankine cycle (ORC) in waste heat utilizing process is investigated. In order to study the performance of the ORC system, the method of mechanism analysis is applied in modeling. In order to achieve both transient performance and steady-state energy saving, a control strategy is proposed for the system by incorporating a Fuzzy control with a PID controller. MATLAB software of Simulink toolbox is applied in this system to study the dynamic characteristics of the object to adapt to parameter changes and anti-interference of control object. Simulations demonstrate that the proposed strategy can obtain satisfactory performance.
