conservative controller meaning in English
谨慎的管理员
Examples
- The conventional variable structure control technique for uncertain system requires that the uncertainty bound is known as a premise to assure robustness . the requirement creates an over - conservative controller and enlarges chattering . the proposed controller regards the influence of unknown disturbances and parameter uncertainties as an equivalent disturbance and generates an on - line estimation used in smc to cancel the slowly varying uncertainties by the mechanism of time delay . the reaching law approach is used to get the conditions and band of quasi - sliding mode . the new methodology offers a robust feedback control with much lower gains and reduces chattering without a prior knowledge of the uncertainty bounds or matched conditions
常规变结构控制用于不确定系统，须利用不确定性界确保系统的鲁棒性，控制器过于保守且抖振变大.本文把未知干扰和参数不确定性的影响等效为名义系统的外界干扰，利用时延技术对干扰进行在线估计，并将估计值引入到变结构控制中，从而抵消掉系统中的慢变不确定性，利用离散趋近律法，推出了准滑动模态的存在条件及其带宽.该方法克服了以往控制方法中须已知不确定性界的限制，且不必满足匹配条件，用较低的控制增益保证了系统的鲁棒性，降低了准滑动模态带即削弱了抖振 - Abstract : the conventional variable structure control technique for uncertain system requires that the uncertainty bound is known as a premise to assure robustness . the requirement creates an over - conservative controller and enlarges chattering . the proposed controller regards the influence of unknown disturbances and parameter uncertainties as an equivalent disturbance and generates an on - line estimation used in smc to cancel the slowly varying uncertainties by the mechanism of time delay . the reaching law approach is used to get the conditions and band of quasi - sliding mode . the new methodology offers a robust feedback control with much lower gains and reduces chattering without a prior knowledge of the uncertainty bounds or matched conditions
