倒立摆控制系统是一个复杂的、不稳定的、非线性系统，是进行控制理论教学及开展各种控制实验的理想实验平台。对倒立摆系统的研究能有效的反映控制中的许多典型问题：如非线性问题、鲁棒性问题、镇定问题、随动问题以及跟踪问题等。通过对倒立摆的控制，用来检验新的控制方法是否有较强的处理非线性和不稳定性问题的能力。利用模糊控制对倒立摆进行控制(Inverted pendulum control system is a complex, unstable, nonlinear system, which is an ideal experimental platform for teaching of control theory and various control experiments. The research of inverted pendulum system can effectively reflect many typical problems in control, such as nonlinear problem, robust problem, stabilization problem, follow-up problem and tracking problem. Through the control of the inverted pendulum, used to test whether the new control method has a strong ability to deal with nonlinear and instability problems. The fuzzy control is used to control the inverted pendulum)

The Interleaved Frequency Division Multiple Ac- cess (IFDMA) scheme is based on compression, repetition and subsequent user dependent frequency shift of a modulated signal. Multiple access is enabled by the assignment of overlapping but mutually orthogonal subcarriers to each user. In this paper it is shown that IFDMA can be regarded as unitary precoded OFDMA with interleaved subcarriers. On the other hand, IFDMA is shown to be a CDMA variant with frequency domain orthogonal signature sequences and chip interleaving. Thus, it combines the advantages of single and multi carrier transmission such as low peak to average power ratio, orthogonality of the signals of different users even for transmission over a time dispersive channel and low complexity. Simulation results show the good performance of coded IFDMA transmission over a mobile radio channel for different data rates.
