【摘要】：考慮逆變器非線性因素對調(diào)速系統(tǒng)的影響,從能量和魯棒性的角度研究了表面式永磁同步電機(jī)(SPMSM)調(diào)速系統(tǒng)。首先推導(dǎo)了包含逆變器的SPMSM系統(tǒng)統(tǒng)一端口受控耗散哈密頓系統(tǒng)(PCHD)數(shù)學(xué)模型,基于能量成形方法和PCHD原理,設(shè)計了SPMSM調(diào)速系統(tǒng)的無源控制器,簡化了控制算法,保證了系統(tǒng)全局穩(wěn)定,逆變器非線性擾動由擴(kuò)張狀態(tài)觀測器進(jìn)行補(bǔ)償。針對速度外環(huán)響應(yīng)速度慢、魯棒性差的問題設(shè)計了非奇異快速終端滑模速度控制器并得到q軸期望的電流。仿真和實(shí)驗(yàn)結(jié)果表明,所提控制方法使轉(zhuǎn)速跟蹤速度快、魯棒性強(qiáng),提高了整個系統(tǒng)的動靜態(tài)性能。
[Abstract]:Considering the influence of inverter nonlinear factors on the speed regulation system, the (SPMSM) speed regulation system of surface permanent magnet synchronous motor (PMSM) is studied from the point of view of energy and robustness. Firstly, the (PCHD) mathematical model of unified port controlled dissipative Hamilton system of SPMSM system including inverter is derived. based on the energy forming method and PCHD principle, the passive controller of SPMSM speed regulation system is designed, which simplifies the control algorithm and ensures the global stability of the system. The nonlinear disturbance of the inverter is compensated by the extended state observer. In order to solve the problem of slow response speed and poor robustness of the speed outer loop, a nonsingular fast terminal sliding mode speed controller is designed and the expected current of the Q axis is obtained. The simulation and experimental results show that the proposed control method makes the speed tracking speed fast and the robustness strong, and improves the dynamic and static performance of the whole system.
