In view of the problems of large overshoot and large oscillation frequency in current furnace temperature control, based on the development of intelligent control theory, expert control, fuzzy control, and neural network control in intelligent control theory are combined with proportional integral derivative (pid) control. The intelligent pid control algorithm is used to carry out numerical simulation and experimental research on these several control algorithms. The results show that the adjustment effect of the intelligent pid control algorithm is significantly better than the traditional pid control algorithm. Among them, the fuzzy self-tuning pid control algorithm and the fuzzy immune pid control algorithm are feasible in the application of furnace temperature control. The neural network pid control algorithm It also has good development and application potential.

Magnetic bearing with redundant structure can regain supporting ability by way of reconstruction under the condition of coil failure. In this paper, the influence of parameters on stiffness is studied by way of simulation and experiment using pid control algorithm, and the reconstruction strategy is proposed. The range of feasible parameters of redundant reconstruction is determined and the weight of the parameters is found out. The control parameter that makes stiffness of magnetic bearing constant is found out. The experimental results are in agreement with the simulation results in tendency, but the experimental results are less than the simulation results.

The paper designs a high power DC motor closed-loop control system, mainly including design of H bridge drive circuit, speed detection circuit and signal conditioning circuit. In order to improve the performance of motor running, one proposes a fuzzy adaptive pid control algorithm. Firstly, one determines the degree of membership of the input values to defined fuzzy sets, then constructs the fuzzy rule table according to experience and experiments, finally, makes defuzzification for every parameter of pid controller, that is, Kp, Ki, Kd. Experiments show that both hardware implementation and software control algorithms are reliable, the running performance of the system is robust before or after adding load.

This paper presents a new intelligent control method which can lower the energy consumption and the pollution risk of electric bicycles. Lowering the energy consumption depends on improving the efficiency of energy transformation, and lowering the pollution risk depends on prolonging the service life of battery. Firstly, we organizes the acceleration model, then quantitative analysis are given to show the relationship between transient current and acceleration time, and the method of lowering the transient current during acceleration is given. Secondly, we determine the speed of motor when it is working at peak efficiency, at which speed the pid control algorithm is used to make the electric bicycles working. This method has been carried out on ARM processor.

Conventional pid control algorithm is difficult to obtain good effect in control of the temperature of FC furnace gypsum calcinations which is characterized by time-varying process, nonlinearity, and big disturbance. In view of the steady-state accuracy of pid control, strong robustness and fast response of fuzzy control, this paper designs fuzzy pid controller to control the pre-drying temperature by overcoming disturbances in the system through online adjustment of the pid parameters. Simulation results show that this control strategy has high-speed quality and stability compared to conventional pid.
