【无人机协同】基于改进灰狼算法实现多峰环境下的多无人机协同路径规划附matlab代码

% 初始化算法参数

num_drones = 5; % 无人机数量

num_iterations = 100; % 迭代次数

num_wolves = 20; % 灰狼数量

alpha = 0.5; % 狼群更新参数

beta = 0.8; % 狼个体更新参数

delta = 0.5; % 灰狼群体更新参数

lb = [0 0]; % 路径范围下限

ub = [100 100]; % 路径范围上限

% 初始化无人机位置

drone_positions = initialize_positions(num_drones, lb, ub);

% 初始化灰狼位置

wolf_positions = initialize_positions(num_wolves, lb, ub);

% 迭代优化路径

for iteration = 1:num_iterations

% 更新灰狼位置

wolf_fitness = evaluate_fitness(wolf_positions, drone_positions);

[best_fitness, best_index] = min(wolf_fitness);

best_wolf = wolf_positions(best_index, 😃;

wolf_positions = update_positions(wolf_positions, best_wolf, alpha, beta, delta, lb, ub);

% 更新无人机位置
drone_positions = update_positions(drone_positions, best_wolf, alpha, beta, delta, lb, ub);

% 显示当前迭代结果
disp(['Iteration: ' num2str(iteration) ', Best Fitness: ' num2str(best_fitness)]);

end

% 最佳路径规划结果

best_path = drone_positions;

disp('Best Path:');

disp(best_path);

% 初始化位置

function positions = initialize_positions(num_positions, lb, ub)

num_dimensions = length(lb);

positions = zeros(num_positions, num_dimensions);

for i = 1:num_dimensions
    positions(:, i) = lb(i) + (ub(i) - lb(i)) * rand(num_positions, 1);
end

end

% 计算适应度（路径长度）

function fitness = evaluate_fitness(wolf_positions, drone_positions)

num_wolves = size(wolf_positions, 1);

num_drones = size(drone_positions, 1);

fitness = zeros(num_wolves, 1);

for i = 1:num_wolves
    distances = zeros(num_drones, 1);
    
    for j = 1:num_drones
        distances(j) = norm(wolf_positions(i, :) - drone_positions(j, :));
    end
    
    fitness(i) = sum(distances);
end

end

% 更新位置

function new_positions = update_positions(positions, best_position, alpha, beta, delta, lb, ub)

num_positions = size(positions, 1);

num_dimensions = size(positions, 2);

new_positions = zeros(num_positions, num_dimensions);

    r1 = rand();
    r2 = rand();
    r3 = rand();
    A = 2 * alpha * r1 - alpha;
    C = 2 * r2;
    D = abs(C * best_position - positions(i, :));
    X1 = best_position - A * D;
    
    r1 = rand();
    r2 = rand();
    r3 = rand();
    A = 2 * alpha * r1 - alpha;

    C = 2 * r2;
    D = abs(C * best_position - positions(i, :));
    X3 = best_position - A * D;
    
    new_position = (X1 + X2 + X3) / 3;
    
    r1 = rand();
    r2 = rand();
    A = 2 * beta * r1 - beta;
    C = 2 * r2;
    D = abs(C * best_position - positions(i, :));
    E = rand();
    new_position = best_position - A * D * exp(beta * E);

The code implementation for such a complex problem requires a detailed understanding of the problem statement, the specific objectives, and the constraints involved. It also requires knowledge of the algorithms and techniques used in the implementation.

However, I can provide you with a high-level outline of the steps involved in implementing such a solution:

1. Define the problem: Clearly define the objectives, constraints, and the environment in which the drones will operate. Identify the number of drones, their initial positions, the target locations, and any other relevant parameters.

2. Initialize the algorithm parameters: Set the number of iterations, the number of wolves (population size), and the range of possible positions for the drones.

3. Initialize the drone positions: Generate random initial positions for each drone within the defined range.

4. Initialize the wolf positions: Generate random initial positions for the wolves within the defined range.

5. Perform the main optimization loop for the specified number of iterations:

   a. Evaluate the fitness of each wolf position based on the objective function (e.g., total distance traveled).

   b. Identify the best wolf position (minimum fitness) and corresponding drone positions.

   c. Update the wolf positions based on the Grey Wolf Algorithm operators (e.g., alpha, beta, delta).

   d. Update the drone positions based on the Grey Wolf Algorithm operators.

   e. Display the current iteration's results (e.g., best fitness).

6. After the loop completes, the best path found by the algorithm represents the optimized path for the drones.

Please note that implementing the Grey Wolf Algorithm and the specific operators (e.g., alpha, beta, delta) requires a deeper understanding of the algorithm and its mathematical formulation. It would be beneficial to refer to research papers or publications that discuss the improved Grey Wolf Algorithm for multi-drone cooperative path planning in multi-peak environments for a more detailed implementation.
