An accurate and automatic weighting method was used to satisfy the command. The system consisted a hopper, a vibration propellant delivering equipment, a particle separation equipment and control system. The main controller and the programmed logic controller were used to control the system to make sure the high precision of particles weighting as host computer and slave computer respectively. The result shows that the method can solve the key technology of the automatic weighting of the small-bore experimental cartridge and offers significance for the automatic weighting of standard particles.

Hardware Structure

According to the practical requirements of filling refrigerants of refrigeration maintenance industries, an high-precision measuring and control system for refrigerant with MSP430 is designed in this paper. High-precision weighing sensor and high-performance amplifier are adopted in the hardware structure, and an improved amplitude-limiting and shake-disappearing filtering algorithm is used in the software data processing. The design is capable of not only achieving the purification and recycling of refrigerant effluent, but also conducting the functions of pressing, vacuumizing and leaking hunting of both high and low pressure. The actual results in the practical refrigeration maintenance industry show that this measuring and control system precision can reach0.5, which is reliable in operation, good in stability and capable of solving the problem that the discharge of waste refrigerant may pollute the environment.

Operating Points

Pulp and paper processes frequently present nonlinear behavior, which means that process dynam-ics change with the operating points. These nonlinearities can challenge process control. PID controllers are the most popular controllers because they are simple and robust. However, a fixed set of PID tuning parameters is gen-erally not sufficient to optimize control of the process. Problems related to nonlinearities such as sluggish or oscilla-tory response can arise in different operating regions. Gain scheduling is a potential solution. In processes with mul-tiple control objectives, the control strategy must further evaluate loop interactions to decide on the pairing of manipulated and controlled variables that minimize the effect of such interactions and hence, optimize controller’s performance and stability. Using the CADSIM Plus™ commercial simulation software, we developed a Jacobian sim-ulation module that enables automatic bumps on the manipulated variables to calculate process gains at different operating points. These gains can be used in controller tuning. The module also enables the control system designer to evaluate loop interactions in a multivariable control system by calculating the Relative Gain Array (RGA) matrix, of which the Jacobian is an essential part.
