Research on Ultrasonic Machining Gap Control Based on Fuzzy Self-tuning PID Parameters Technology

The working principle and measurement of ultrasonic machining gap is analyzed in this paper. A stable machining gap between the tool and workpiece must be maintained for improving processing accuracy and efficiency. Therefore, a fuzzy self-tuning PID parameters controller for ultrasonic machining tool feed system is designed, by means of using Matlab /Simulink simulation experiment, in this paper.

Model Driven PID Controller in Water Heater System

PID controller has been widely used as one of the basic property controllers in industry. However, tuning PID parameters is not simple and also has a few problems in handling slow response systems, such as boiler. Therefore, the Model Driven PID (MD PID) control is designed for solving these problems, especially for plants or processes with slow response. The MD PID is using the model of the plant itself as the basic model of the controller. In this research, we will show the performance of water heater system step response with MD PID controller compared to the conventional PID controller (PI controller). The MD PID closed-loop system is expected to give fast response, stable, and no overshoot.

Study of PID Control Algorithm Based on the Critical Ratio Method

PID control is one of the earliest control strategy and till has the most widely use in the industrial process at the present. The PID parameter tuning and optimizing decide what the control performance of the control system can achieve. PID parameter tuning is the core content in control system design. In this paper, aiming at the complexity of PID parameter tuning process, the critical ratio method was optimized and propose a simple and effective method of tuning PID parameters. By simulation, this method turn out to be simple and effective, good real-time performance.

Effective PID Parameters Self-Tuning Rule Based on Internal Model Control

The methods of self-tuning PID parameters are widely used in industry process control. This paper elaborated the principle and design of internal model control, and it is used for PID parameters self-tuning. By simulation, for a time-delay inertial system, the step response curses are obtained with different methods of self-tuning PID parameters. Compared and analyzed the curses, it shows that the present method of self-tuning IMC-PID parameters has a good performance in the time-delay inertial system. It has great potential for practical applications.
