The tramcar runs upward and downward frequently and the load varies with practical requirements, the operating conditions of the hydro-viscous winch are very complex, so the ordinary PID controller cannot meet the requirements of the winch. In order to control the speed of the hydro-viscous winch precisely and obtain perfect starting speed, a new fuzzy-PID control system was designed, the starting process of the winch and the speed regulation characteristics were simulated by using MATLAB. The results show that the designed control system can meet the requirements of the winch well. It can not only obtain perfect starting speed, but also adjust the running speed precisely. Research achievements of this work provide theoretical basis for optimal design and practical applications of the hydro-viscous winch.

Fuzzy Pid Controller

Fast-steering mirror system demands higher accuracy and fast responding speed to track targets, but the conventional PID controllers cannot meet the demands. Instead, the fuzzy PID control can greatly improve the capturing and tracking capacities to high-speed dynamic targets. So we apply the fuzzy-PID controller in the positioning loop of the stabilized system, not only improving the transient process of the control system and decreasing the overshoot, but also enhancing the accuracy of tracking stabilization and response. At the end, simulations were performed to test the effectiveness of this method through the MATLAB platform.

Speed Fluctuation

As a rotational speed controller, a hydro-viscous clutch (HVC) is usually used in the constant pressure water supply system to maintain the needed water pressure constant. However, when the hydro-viscous clutch is working, it often suffers from the problem of output rotational speed fluctuation since the spool of proportional relief valve can easily get stuck. Consequently, water pressure will fluctuate too. A special pump control system of HVC was proposed based on the Fuzzy-PID controller for the purpose of reducing the fluctuation rate. The MATLAB simulation was carried out according to the mathematical model and the results show that the Fuzzy-PID control strategy is superior to traditional PID control. The corresponding experiment was performed and the result indicate that through applying the Fuzzy-PID controller based pump control system, the rotational output speed fluctuation of HVC can be inhibited from ±60π to ±6π rad/min, and the water pressure fluctuation is dropped from ±0.1 to ±0.002 MPa.

The simulation results show that the fuzzy self-tuning PID controller has good dynamic response curve, short response time, small overmodulation, high steady state precision, and good dynamic and static performance by comparing with the traditional PID controller. Therefore temperature and humidity control of tobacco leaf roasting will perfectly improved by fuzz PID control.

Tuning Rules

The PID controllers can be seen in lots of fields, but some complex control system cannot be controlled to achieve a desired performance index. A design method of the fuzzy PID controller that is based on the fuzzy tuning rules and formed by integrating two above control ideas is proposed in this paper. The design procedure about fuzzy PID control can be divided two steps: the first step is to build the fuzzy tuning rules by analysis, and to obtain the parameters of PID controller by reasoning, and then the control action can be determined by the PID control law. The simulation results and the practical control effects show that the compound fuzzy PID controller has better performance than that of the conventional PID control system and meet the practical demands.
