⛄ 内容介绍

Nature-Inspired Optimization Algorithms provides a systematic introduction to all major nature-inspired algorithms for optimization. The book's unified approach, balancing algorithm introduction, theoretical background and practical implementation, complements extensive literature with well-chosen case studies to illustrate how these algorithms work. Topics include particle swarm optimization, ant and bee algorithms, simulated annealing, cuckoo search, firefly algorithm, bat algorithm, flower algorithm, harmony search, algorithm analysis, constraint handling, hybrid methods, parameter tuning and control, as well as multi-objective optimization. This book can serve as an introductory book for graduates, doctoral students and lecturers in computer science, engineering and natural sciences. It can also serve a source of inspiration for new applications. Researchers and engineers as well as experienced experts will also find it a handy reference.

⛄ 部分代码

function sdot = quadEOM_readonly(t, s, F, M, params)

% QUADEOM_READONLY Solve quadrotor equation of motion

%   quadEOM_readonly calculate the derivative of the state vector

%

% INPUTS:

% t      - 1 x 1, time

% s      - 13 x 1, state vector = [x, y, z, xd, yd, zd, qw, qx, qy, qz, p, q, r]

% F      - 1 x 1, thrust output from controller (only used in simulation)

% M      - 3 x 1, moments output from controller (only used in simulation)

% params - struct, output from nanoplus() and whatever parameters you want to pass in

%

% OUTPUTS:

% sdot   - 13 x 1, derivative of state vector s

%

% NOTE: You should not modify this function

% See Also: quadEOM_readonly, nanoplus

     0.25, -0.5/params.arm_length,                      0];

prop_thrusts = A*[F;M(1:2)]; % Not using moment about Z-axis for limits

% Assign states

% Acceleration

accel = 1 / params.mass * (wRb * [0; 0; F] - [0; 0; params.mass * params.grav]);

% Angular velocity

K_quat = 2; %this enforces the magnitude 1 constraint for the quaternion

% Angular acceleration

omega = [p;q;r];

pqrdot   = params.invI * (M - cross(omega, params.I*omega));

% Assemble sdot
