the system's transfer function is acquired according to the step response curve . the influence of the system's pressure balance time affected by the steady and unstable state's increasing is discussed, the conclusion has practice meaning 深入客觀地探討了不同的加壓速率利加壓幅值以及分階段加壓對卸荷閥性能測試系統(tǒng)壓力平衡時間的影響,獲得了有實踐指導(dǎo)意義的結(jié)果。
the innovative ideas in this paper is to replace the linear fixed-gain pid controller for a nonlinear pid controller . based on the step response curves of conventional control system, we analyze the ideal variety of three gains in different times and construct the simulated curves of proportional, intergral and derivative gain . the controllers has considered all sorts of imperceptible factors affecting the servo performances in a lpmsm servo system, which include the parametric uncertainties brought by the changes of the mobile mass, the dynamitic performance of the system and the size of input . to solve the problem of so many unknown parameters, we use transmit arithmetic to find the parameters which are fit for the system . to keep the robust and stable performance 本文的創(chuàng)新之處在于,將傳統(tǒng)的固定增益的pid控制器用非線性pid控制器來代替,并在此基礎(chǔ)上,就一般控制系統(tǒng)的階躍響應(yīng)曲線,分析了在不同響應(yīng)時間階段pid的三個增益調(diào)節(jié)參數(shù)的理想變化情況,并根據(jù)這些理想變化,分別給出了比例、積分、微分增益參數(shù)的一種連續(xù)的非線性擬和函數(shù)。在分析雙位置環(huán)時,仔細考慮了能使系統(tǒng)性能變壞的各種因素,如系統(tǒng)的動態(tài)性能及控制出入能量的大小等等。
