    摘要:

    針對移動機器人傳統(tǒng)路徑跟隨控制方法需要人工調(diào)校參數(shù)、缺乏自主優(yōu)化能力的問題,提出了一種基于啟發(fā)式動態(tài)規(guī)劃(Heuristic dynamic programming, HDP)的路徑跟隨控制方法。首先,設計履帶式機器人路徑跟隨控制系統(tǒng)結(jié)構(gòu),建立了誤差狀態(tài)方程;其次,提出了一種基于HDP算法的路徑跟隨控制方法,綜合誤差性能指標和跟隨穩(wěn)定性指標設計了回報函數(shù),采用多層前饋神經(jīng)網(wǎng)絡逼近評價器和執(zhí)行器,并推導了網(wǎng)絡參數(shù)的在線優(yōu)化規(guī)則;最后,通過數(shù)值仿真和系統(tǒng)試驗驗證了HDP方法的路徑跟隨性能。試驗結(jié)果證明,基于HDP算法的控制器跟隨直線的平均誤差絕對值為0.04m、均方根誤差為0.06m;跟隨鈍角轉(zhuǎn)向曲線的平均誤差絕對值為0.01m、均方根誤差為0.06m;跟隨銳角轉(zhuǎn)向曲線的平均誤差絕對值為0.03m、均方根誤差為0.09m。該方法不需要對控制參數(shù)進行反復調(diào)試就能夠獲得較好的控制效果,提高了移動機器人路徑跟隨控制方法的環(huán)境適應性和自主優(yōu)化能力。

    Abstract:

    Aiming at the problem that the traditional path following control method of mobile robot requires manual tuning parameters and lacks of self-optimization ability, a path following control method based on heuristic dynamic programming (HDP) was proposed. Firstly, the error state equation of the path following system was established based on the structure of tracked robot system. Secondly, a path following controller based on HDP algorithm was proposed. The return function was designed by synthesizing the error performance index and the following stability index. A multi-layer feedforward neural network was used to establish the actuator and evaluation modules, and the online optimization rules of network parameters were derived. Thirdly, the path following performance of HDP method was verified by numerical simulation and system test. The experimental results showed that the controller based on the HDP algorithm of the mean absolute error was 0.04m and the root mean square error was 0.06m when following a straight line, 0.01m and 0.06m when following a obtuse angle steering curve, and 0.03m and 0.09m when following an acute angle steering curve, and the method based on HDP can obtain high precision control effect without repeated debugging control parameters, and it improved the environmental adaptability and autonomous optimization ability of the path following control method for mobile robots.
