Ozone is considered as one of the strongest oxidizing agent, yet it leaves no residues that are harmful to global environment. In this paper, the close loop control of ozone generator has been studied. The main concern of this issue is to achieve desired ozone concentration. Due to the ozone generation process is a complex nonlinear multivariable system, which is difficult to model and regulate, thus...
This paper designed a control system of LD pumped Nd(3+) : YVO4 solid-state laser based on AduC7028, in which NTC and BPW34 photo electricity diode are used as the sensor of temperature and light-intensity respectively. Adopting temperature-control logic combined with digital PID and power-feedback, the stability of the output power and the S/N has been largely improved.
The paper presents a process optimal control scheme of sheet metal forming springback based on evolutionary strategy. The springback prediction model is established on orthogonal test analysis. The evolutionary strategy based on linear transformation fitness function is used as optimization algorithm, the smallest sheet metal forming springback as the goal, to complete the process parameter optimization...
