摘 要:風(fēng)洞調(diào)速系統(tǒng)在不同轉(zhuǎn)速下的負載變化較大,這給電機控制算法帶來了極大挑戰(zhàn)。針對風(fēng)洞調(diào)速系統(tǒng)穩(wěn)態(tài)運行速度控制精度高,及動態(tài)運行姿態(tài)調(diào)整速度超調(diào)小的要求,設(shè)計了一種參數(shù)自適應(yīng)控制的調(diào)速系統(tǒng)。建立轉(zhuǎn)速控制模型和風(fēng)洞負載模型,分析風(fēng)洞負載速度控制不能全速范圍使用一組調(diào)節(jié)器參數(shù)的問題。在此基礎(chǔ)上,引入當(dāng)前速度,針對性的設(shè)計不受工況限制的自適應(yīng)速度閉環(huán)控制。仿真結(jié)果表明,設(shè)計的基于參數(shù)自適應(yīng)的速度閉環(huán)的控制系統(tǒng),在滿足穩(wěn)態(tài)控制精度的同時,速度動態(tài)變化時幾乎無超調(diào),可以使一組控制器參數(shù)滿足不同工況的速度控制性能。

Abstract: The load of the wind tunnel speed regulation system varies greatly at different speeds, which poses a great challenge to the motor control algorithm. In response to the requirements of high steady-state operation speed control accuracy and small speed overshoot during dynamic operation attitude adjustment in the wind tunnel speed regulation system, a speed regulation system with parameter adaptive control has been designed. Establish a rotational speed control model and a wind tunnel load model, and analyze the problem that a set of regulator parameters cannot be used throughout the full speed range for wind tunnel load speed control. On this basis, the current speed is introduced and a targeted adaptive speed closed-loop control that is not restricted by working conditions is designed. The simulation results show that the designed speed closed-loop control system based on parameter adaptation not only meets the steady-state control accuracy but also has almost no overshoot when the speed changes dynamically, enabling a set of controller parameters to meet the speed control performance under different working conditions.
Key words: wind tunnel speed regulation; asynchronous motor; parameter adaptive control; steady-state accuracy; speed overshoot
