Stability analysis of ship electrical automation control

舰船电气自动化控制中受到负载增益的持续性扰动因素影响,导致输出参量存在扰动误差,需要进行稳定性控制设计,提出一种基于混沌小扰动抑制的舰船电气自动化控制稳定性设计方法。构造舰船电气自动化控制的等效电路模型,以系统效率、输出功率增益、电压和供电频率等参量为约束量,进行控制目标函数构建,采用混沌参数调制和扩频处理方法进行舰船电气控制中的小扰动抑制,采用混沌同步控制方法进行舰船电气稳定性控制,并进行了控制器的电路设计。测试结果表明,采用该方法进行舰船电气自动化控制的稳定性较好,输出增益较大,抗扰动能力较强。

The ship electrical automation control is affected by the persistent disturbance factors of load gain, which leads to the disturbance of output parameters, so the stability control design is needed. A method of ship electrical automation control stability design based on chaotic small disturbance suppression is proposed. The equivalent circuit model of ship electrical automation control system, in order to gain efficiency and output power, voltage and frequency of power supply parameters such as a restriction, to construct the objective function by using chaotic parameter modulation and spread spectrum processing method for ship electric control in the small disturbance suppression, using chaotic synchronization control method of ship electrical stability. And the circuit design of the controller. The test results show that the method has better stability, higher output gain and stronger anti disturbance ability..
