As a kind of mature and effective ship stabilizer, fin stabilizers have been applied on various ships more widely. Fin stabilizers play an important role in improving ship seakeeping quality, ensuring equipments in normal working conditions, making crews work comfortably, improving ship seaworthiness and so on.This thesis studies ship fin stabilizing control system, and makes

Paper color is one of the external quality indicators which can be discerned by human eyes. As the improvement of people’s living condition, the need of color on paper has been shown more diversity. At the same time, the demand of the color uniformity on paper is becoming stricter and stricter. As a result, the

PID control algorithm is very common in the industrial control area,at any givenmoment,the parameter characteristics of the controlled system may change, Thetraditional method of PID parameter tuning has been unable to meet real-time, accuratecontrol conditions, Therefore, the problem need to address is to adjust PID parametersonline. Microprocessors and sensors has been a substantial increase in

Multi-variables、strong coupling、large time-delay and nonlinear are characteristics ofcity heating process control, and the mathematic model are ascertained difficultly. Based on in-depth analysis on pros and cons of generalized predictive control (GPC) algorithm, This paperapply the GPC implicit PID control algorithm in substation heating process control.Generalized predictive control (GPC) has been widely applied to temperature control,

The injection molding machine is a kind of fast Molding equipment which can produce products through inject melted raw materials to mould and then cooling. Its working process mainly includes shut the mould, injection, pressure-keeping, cooling and open the mould. The key to affect the quality of products is injection and pressure-keeping process controlled by

This thesis investigates two control methods for the stabilization of an inverted pendulum system, the Fuzzy and PID.it also addresses some of the potential benefits of using both controllers to control an inverted pendulum system. Considering which technique and control method is best for the control of pendulum angle and the cart’s position. The Inverted

Time-lag is actual production of more common phenomenon, because oneself the performance differences, also significantly impact on the quality of the products. Because delay phenomena exists, make the control system while working stability appear problem, may appear overshoots big, adjust time long wait for a phenomenon. So, delay process control methods has been control theory
