了基于性能指標(biāo)切換的多模型 預(yù)測(cè)控制算法，這種方法通過(guò)在多個(gè)操作點(diǎn)附近獲取的多個(gè)線性模型來(lái)設(shè)計(jì)多個(gè)線性控制器，同時(shí)根據(jù)所提的控制器選擇方法來(lái)達(dá)到非線性控制。將所提基于性能指標(biāo)切換的多模型 預(yù)測(cè)控制算法施加到仿真系統(tǒng)中，分別進(jìn)行了設(shè)定點(diǎn)跟蹤和有干擾兩種不同情況的仿真。結(jié)果表明，所提算法多模型非線性預(yù)測(cè)控制算法與普通的DMC相比具有更加良好的穩(wěn)定性和收斂性，并能做到無(wú)偏跟蹤。
