Typical Applications
- Increasing the simulation speed of complex hybrid systems consisting of both dynamic systems and discrete events: The use of variable step solver suffers from the disadvantage of greatly slowing the simulation for complex hybrid systems; meanwhile, the use of fixed-step solvers, improves the simulation speed, giving incorrect results because of the delays it takes into account for the discrete events (asynchronous with the simulation step) to the next simulation cycle, causing accumulating errors and phase shifts.
- Real-time simulation of hybrid systems: Only fixed-step solvers can be used for automatic code generation; however, a standard fixed-step solver of Simulink yields erroneous results, then applied to hybrid systems; and this may accumulate and cause drift and big phase shift. On the other hand, RT-Events applies a compensation algorithm to discrete events in real-time, resulting in a great precision.
- Real-time simulation of firing pulse units of power electronics: In rapid prototyping of power electronic systems, it is difficult to convert the controller outputs to switching signals that are sent to time-stamped digital outputs, by using comparators and timer blocks. The use of standard Simulink blocks causes high jitter because the lack of any timing information; when simulated at fixed-step in the order of 10 to 100 s, the firing pulses cannot be generated precisely unless timing information about the switching and state transitions is added to the switching state; and this is enabled by RT-Events.
