Along with the rapidly advancement of the computer hardware and software technology, special-purpose simulation computer system has gradually failed to keep pace with the developing and application trend of simulation technology. So in its development process, simulation computer gradually got rid of the customization road, gradually choose a common path. KDRTS (Ke Da real time simulation system),...
Plants simulation is one of the research domains which are full of challenges. Since the L-System and IFS both have limitations in the field of plant inflorescence simulation, the images of plant organs generated by using L-System or IFS are lack of enough real changes. The paper proposed a method that integrated iterated function system with L-System using Visual Basic 6.0 as development environment...
The linear quadratic regulator (LQR) control law is designed for the stabilization of the three Euler angles of a helicopter. The digital closed-loop simulation is conducted with the helicopter model, the actuator models and the designed controller in loop. The robust controller is programmed into a real-time software which is downloaded into the flight control computer. The hardware-in-loop simulation...
