( 3 ) the theory of morden optimal control is used for the controller design of the active vibration isolation system . two algorithms , instantaneous optimal control and linear quadratic gauss optimal control , have been discussed and compared . an instantaneous optimal closed - loop control algorithm in structural space is derived by using the newmark scheme ( 3 )應(yīng)用最優(yōu)控制理論設(shè)計(jì)控制器,對(duì)瞬時(shí)最優(yōu)控制和線性二次型gauss ( lqg )閉環(huán)控制方法進(jìn)行研究和對(duì)比,并導(dǎo)出構(gòu)形空間內(nèi)的瞬時(shí)最優(yōu)閉環(huán)控制算法。
Based on the pim , the closed - loop and closed - open - loop control algorithm under the instantaneous optimal control strategy are acquired , so it has practical significance in active control . at last , the simulation analysis of numerical examples demonstrate that the methods are superior to the conventional numerical methods , and has excellent precision , efficiency and stability 最后,在c + + builder環(huán)境下編制各算法程序,算例仿真結(jié)果表明,本文算法優(yōu)于經(jīng)典數(shù)值解法,有很好的計(jì)算精度、效率及穩(wěn)定性,且精度易于控制;同時(shí),用精細(xì)積分下結(jié)構(gòu)控制算法進(jìn)行結(jié)構(gòu)控制模擬,得出較理想控制效果。
