Two single chip microcomputers C8051F020 are used to design software and hardware of dynamic measuring and controlling system of electromagnetic valve driver. In the design of hardware circuit, RC filter circuit and photoelectricity coupler TLP550(TOSHBAO) are designed to achieve the goals including filtering high frequency disturbances, collecting high frequency signals, preventing external disturbances...
Drum water level control of Industrial boiler is one of main technical specifications for boiler control system. Because of the phenomenon of False Water Level (FWL), according to the human thinking processes in manual adjustment, three measurement signals, i.e. drum water level, water supply flow and steam flow are introduced, and a fuzzy control algorithm is used to calculate the control volume,...
The resin abrasive products hardening furnace is important electric heating equipment. The hardening furnace is a controlled object with time delay and non-linear characteristics, and the temperature has a one-way nature. So it is difficult to establish its accurate mathematical model. Because the conventional PID regulator has fixed parameters, the control effects are often poor. In this paper, the...
Design method of parameters adaptive controller for a giant magnetostrictive actuator is researched. According to the linear dynamic model built based on the working principle of giant magnetostrictive actuator, a parameters adaptive controller of the system is designed by integrator backstepping technology, and a strict theory proof is provided. The designed parameters adaptive controller makes sure...
Feedback linearization technique is a relative mature design technique in nonlinear control system theory, the backstepping technique is a controller design technique which recently gets much favor. The feedback linearization based on backstepping technique is the combination of the two techniques mentioned, it uses backstepping design process, designs a sequence of ??virtual?? systems of relative...
The synchrodrive is the important part in the gantry moving type milling machining centers. First, robust compensation are designed for linear servo systems with parameter variations, friction disturbance and no linearity at low speed. Then, a synchronization control strategy is presented based on fuzzy-coordinated control according to the double position synchronized drive of numerical control (NC)...
In order to describe the movement of multi-robot queue, the model of formation is defined in view of relative poses of multiple mobile robots. The idea of switching control is introduced based on leader-following schema. The front point and rear point of the axis of leading robot is determined as reference points by the following robot. The sub-controller is designed corresponding to the reference...
A new control method based on potential function is presented, which can effectively control the movement of multi-agent system with multiple leaders. The system includes two kinds of agent: leader and follower. Leader has the knowledge about the environment and is attracted by the object, but follower is only affected by the information about the neighbor. To make the system to the anticipation,...
