摘要

Based on large power interior permanent magnet synchronous motor ( IPMSM ) of gun drive sys-tem, an approach based on the iq feedback was proposed to solve the higher degree torque-current equation which could effectivly simplify the torque-current equation and the MTPA control was achieved.The simula-tion results indicate the dynamic performance of drive system was improved effectivly by using iq feedback methed, which had feature of high caculation accuracy , and the proposed algorithem has the merit of sim-plicity and engineering practicability.The requirements of gun drive system such as fast respond , anti-over-load, wide speed regulation range , lager output power , high rotation rate were satisified by using this method .%以大功率内装式PMSM为执行元件的火炮方位驱动系统为研究对象，提出了一种采用交轴电流i q 反馈求解转矩电流高次方程的方法，合理简化了高次方程，实现了最大转矩电流比控制。仿真结果表明该方法可有效提高驱动系统的动态性能，具有计算精度高、算法简单、易于工程实现等特点，满足了火炮驱动系统响应快、抗过载、调速范围宽、输出功率大、转速高等指标要求。
