With regard to parameter estimation , the capacity of different models and parameter estimation methods should be tested against the specific market and sample data 在參數(shù)估計(jì)方面,應(yīng)針對(duì)具體市場(chǎng)和樣本數(shù)據(jù),檢驗(yàn)各種模型和參數(shù)估計(jì)方法的能力。
The optimal solu tion of real control can be obtained by means of iteratively solving the op timiz ation problem based on bilinear model and parameter estimation problem 在模型與實(shí)際存在差異的情況下,通過求解修正的基于雙線性模型的優(yōu)化問題和參數(shù)估計(jì)問題,給出了實(shí)際問題的最優(yōu)解。
Since the problem of feature extraction from 2 - d radar data can be approached as a parametric modeling and parameter estimation problem , the 2 - d type - discriminated geometric theory of diffraction based ( td - gtd ) model that discriminate between the localized and distributed scattering centers of the target is presented 在對(duì)目標(biāo)散射中心的建模與參數(shù)估計(jì)中,提出采用更貼近散射機(jī)理的、特征含量更為豐富的二維散射中心模型?區(qū)分局域性與展布式散射中心類型的幾何繞射理論( td - gtd )模型。
Even with unmodeled dynamics and bounded disturbances presented the controller has good robust performance without need of correct dynamic model and parameter estimation . the designed controller has applied to a model of three - generators hvdc system , and the simulations are performed with netomac 并且這種控制器的設(shè)計(jì)不需要有精確的系統(tǒng)動(dòng)態(tài)模型,不需要未知參數(shù)來滿足線性依賴條件,不需要具體的系統(tǒng)參數(shù)估計(jì),即使存在未建模動(dòng)態(tài)和有界擾動(dòng),系統(tǒng)仍然具有很好的魯棒性。
