MVU

Spread spectrum merupakan sistem dimana sinyal yang dikirimkan memiliki bandwidth yang jauh lebih lebar daripada bandwidth sinyal informasinya sendiri. Proses pelebaran bandwidth sinyal informasi ini dilakukan pada sisi pengirim dan disebut spreading. Sebaliknya, proses penyempitan kembali bandwidth sinyal informasi dilakukan di sisi penerima, dan disebut despreading. Pada gambar 1 berikut menunjukkan proses yang terjadi pada sistem spread spectrum.

The PID controller is the most widely used controller in industrial systems. However, appropriately tuning a PID controller is not an easy task although it has only three parameters at most. This submission provides a tool for beginners to learn PID tuning.

说明：  本例采用最优控制的方法,利用二次型性能指标,保证小车所滑过的距离和整个过程所花费的能量达到最优值.程序包括initial.m,yjlqgctr.m,cartoon.m,simlqgyj.slk等文件(cases using the optimal control methods, using quadratic performance indicators, Trolley assured by sculpting the distance and the whole process will have to spend energy to achieve the optimal values. procedures include initial.m , yjlqgctr.m, cartoon.m, simlqgyj.slk documents)

differentialDrive robot takes the robot s start and goal positions and orientations and the robot s trajectory and plots this on a graph
