In this paper, a static volt-ampere-reactive compensator (SVC) composed of fixed capacitor-thyristor controlled reactor (FC-TCR) is employed to regulate the terminal voltage of self-excited induction generator (SEIG) in the purpose of controlling the output power. In addition, the speed of the generator is adjusted by robust proportional-integral-derivative (PID) in order to regulate the frequency. Fractional order PID (FOPID) and Tilt-PID (T-PID) controllers are proposed to adjust the triggering angle of FC-TCR. The objectives of the paper are to design the optimal voltage controller with a robust PID frequency controller and to maintain the output power at a desired level in case of voltage sensor faults. In this regards, nonlinear autoregressive network with exogenous inputs (NARX) and small signal models of the SEIG are constructed where triggering angle and generator speed are inputs, whereas terminal voltage and frequency are outputs, respectively. Training of the NARX model is achieved with a high regression value (R² = 0.99) where the accuracy of the small signal voltage model is 82%. After comparing the accuracy of the models, NARX-based fault detection architecture and fault tolerant controller are designed in order to avoid incorrect control of the output power. To establish the effectiveness of proposed fault tolerant controllers, simulation studies are conducted using particle swarm optimization (PSO). The designed controllers are performed experimentally on three-phase 5.5 kW, 400 V, 50 Hz, balanced loaded SEIG to confirm the effectiveness. The system is tested with proposed controllers under the healthy sensor, faulty sensor and dynamic reference conditions. Results give good agreement with simulation results and designed fault tolerant T-PID controller performs better tracking dynamics with small deviations whether the voltage sensor is faulty or not.

本文采用由固定电容晶闸管控制电抗器（FC-TCR）组成的静态伏安无功补偿器（SVC）来调节自激感应发电机（SEIG）的端电压。输出功率。另外，发电机的速度通过鲁棒的比例积分微分（PID）进行调整，以调节频率。提出了分数阶PID（FOPID）和Tilt-PID（T-PID）控制器来调整FC-TCR的触发角度。本文的目的是设计具有鲁棒PID频率控制器的最佳电压控制器，并在发生电压传感器故障时将输出功率保持在所需水平。在这点上，构建带有外部输入（NARX）和SEIG的小信号模型的非线性自回归网络，其中分别以触发角和发电机速度为输入，而输出端电压和频率为输出。NARX模型的训练具有较高的回归值（R^2个 = 0.99），其中小信号电压模型的精度为82％。在比较了模型的准确性之后，设计了基于NARX的故障检测架构和容错控制器，以避免对输出功率的错误控制。为了建立建议的容错控制器的有效性，使用粒子群优化（PSO）进行了仿真研究。设计的控制器在三相5.5 kW，400 V，50 Hz，平衡负载SEIG上进行实验，以确认其有效性。在健康传感器，传感器故障和动态参考条件下，使用建议的控制器对系统进行了测试。结果与仿真结果吻合得很好，无论电压传感器是否有故障，设计的容错T-PID控制器都能以较小的偏差实现更好的跟踪动态。
